Book cover of The Girl Beneath the Sea

Nicholas Harvey Author Of Twelve Mile Bank

From my list on female scuba diving thrillers and mysteries.

Why am I passionate about this?

My wife suggested we try scuba diving while on holiday in Grand Cayman. We were already falling in love with the island, and the incredible experience underwater opened a whole new world to us. From that moment on, our yearly travels changed completely. Our destination choices were now based upon diving opportunities. That was twenty years ago. Today, I’m a certified divemaster with dives all over the US (including Hawaii), the Caribbean (including Cuba), Australia, and even Iceland. Throw in my sense of adventure as a former race car driver, motorcycle rider, and outdoor adventurer, and I had plenty of personal experiences to create the AJ Bailey series.

Nicholas Harvey Why Nicholas loves this book

I’d already written several books in my AJ Bailey series when Girl beneath the Sea came out. With the might of a large publisher behind the book it hit best-seller lists and proved to me that I was writing books with a subject matter appealing to a broad audience.

Mayne’s protagonist, Sloan McPherson, is a police diver in Florida, who takes cases much farther than her role suggests. She’s an imperfect person with baggage and problems, but her gutsy determination drives the stories forward.

I dive into each new book in the series on the day they’re released.

What is this book about?

An Amazon Charts bestseller.

For a Florida police diver, danger rises to the surface in an adventurous thriller by the Wall Street Journal bestselling author of The Naturalist.

Coming from scandalous Florida treasure hunters and drug smugglers, Sloan McPherson is forging her own path, for herself and for her daughter, out from under her family’s shadow. An auxiliary officer for Lauderdale Shores PD, she’s the go-to diver for evidence recovery. Then Sloan finds a fresh kill floating in a canal―a woman whose murky history collides with Sloan’s. Their troubling ties are making Sloan less a potential witness than a suspect.…

Nicholas' book list on female scuba diving thrillers and mysteries

Nicholas Harvey Why Nicholas loves this book

Okay, so Deep isn’t specifically about women, or scuba diving – it tackles freediving – but includes females and anyone who loves diving in any form should read this book. The meticulous research into the physiology and psychology of human beings underwater is simply fascinating. Nestor ventures off into all kinds of territory, from octopus intelligence; to whales conversing; to humans holding a single breath for an inhuman amount of time.

Freediving is the common theme in the book, but it is far more than that. This is an in-depth study of life beneath the waves from an intriguing perspective.

By James Nestor ,

Why should I read it?

1 author picked Deep as one of their favorite books, and they share why you should read it.

What is this book about?

From the author of the international Bestseller Breath

Covering a diving championship in Greece on a hot and sticky assignment for Outside magazine, James Nestor discovered free diving. He had stumbled on one of the most extreme sports in existence: a quest to extend the frontiers of human experience, in which divers descend without breathing equipment, for hundreds of feet below the water, for minutes after they should have died from lack of oxygen. Sometimes they emerge unconscious, or bleeding from the nose and ears, and sometimes they don't come up at all.

The free divers were Nestor's way into…


Book cover of Deep Shadow

Sharon Ward Author Of In Deep

From my list on mysteries set on a tropical island.

Why am I passionate about this?

Even as a kid, I was intrigued by the underwater world, so as an adult, I learned to scuba dive. I took to it like a fish to water, and my husband and I spent the next several years traveling to tropical islands to experience the local dive conditions whenever possible. I loved learning how every island had a different culture and a different undersea environment. Since I love tropical islands, scuba diving, mysteries, and adventure stories, these books really hit my sweet spot.

Sharon's book list on mysteries set on a tropical island

Sharon Ward Why Sharon loves this book

As a long-time diver, I was enthralled by the details of the undersea world. Set on the tropical island of Bonaire, a scuba diver’s paradise, this book introduces the reader to two great characters, divemasters Boone Fischer and Emily Durand. 

The author interweaves Boone and Emily’s budding romance with compelling descriptions of the diving and the sea life they encounter. The way the two divemasters get involved in the search for the drug submarine at the heart of the mystery is plausible. Twists and turns on every page keep the reader guessing about the fate of the sub, its crew, the cruise ship, and most critically, the two highly appealing divemasters who use every skill they have to avert disaster. I was instantly hooked on the series.

2 authors picked Deep Shadow as one of their favorite books, and they share why you should read it.

Scuba divers travel from all over the world to visit the little island of Bonaire, with its crystal-clear waters and a host of beautiful marine life. After three years in the “Diver's Paradise”, divemaster Boone Fischer thought he’d seen it all; but on a routine afternoon dive, he spots something that will turn his tranquil life upside down.

From the arid shores of the ABC Islands to the tropical jungles of Venezuela—from the ocean depths of the Southern Caribbean, to the lush islands of the Northern Leewards,…

Nicholas' book list on female scuba diving thrillers and mysteries

Nicholas Harvey Why Nicholas loves this book

Kathy’s series – which I wish she’d continue one day – inspired me to include my passion for scuba diving in my novels. Her main character, Hannah Sampson, is a member of the Denver Underwater CSI team, who’s asked to help the police in the British Virgin Islands investigate a case. Needless to say, she stays on the island for the following books and becomes embroiled in hair-raising cases that challenge her above and below the water.

Kathy published her series at a time when very few novels centered around diving, and certainly didn’t include a female protagonist. I found her work transported me to the islands, and enthused me to create AJ Bailey and subsequently, Nora Sommer.

An Underwater Investigation featuring C.S.I. diver Hannah Sampson.

Summoned to the sun-drenched beaches of the British Virgin Islands, Hannah Sampson is fully prepared to face unknowable dangers beneath the crystal-clear waters of an idyllic paradise. But the possibility of murder runs deeper and darker than the sea itself. Her police commissioner's son-an expert diver and researcher-was found dead, pinned under the submerged wreckage of a cargo ship. Whatever the victim was looking for, he found.

Whatever he found was the death of him. Now Hannah must discover for herself what lies beneath-a…


Book cover of Holding Their Breath: How the Allies Confronted the Threat of Chemical Warfare in World War II

Thomas I. Faith Author Of Behind the Gas Mask: The U.S. Chemical Warfare Service in War and Peace

From my list on chemical weapons.

Why am I passionate about this?

When I first enrolled in college, I expected to be a science major who was also interested in history, but I ended up becoming a history major who was also interested in science. I earned my Ph.D. in history from George Washington University in Washington, DC, after earning my B.A. from Temple University in Philadelphia, PA. My Ph.D. dissertation on the U.S. Army Chemical Warfare Service during WWI and the 1920s became the basis for my book Behind the Gas Mask.

Thomas' book list on chemical weapons

Thomas I. Faith Why Thomas loves this book

This book provides an answer to a question that historians of arms control have asked since WWII ended: Why had the use of chemical weapons on the battlefield not become widespread in WWII, in the same manner it had in WWI? Focusing on Britain, Canada, and the United States, Holding Their Breath explores Allied reluctance to use chemical weapons and their formulation of a joint policy on chemical warfare. M. Girard Dorsey shows that the potential for chemical warfare in WWII profoundly influenced the course of the war’s events.

By M. Girard Dorsey ,

Why should I read it?

1 author picked Holding Their Breath as one of their favorite books, and they share why you should read it.

What is this book about?

Holding Their Breath uncovers just how close Britain, the United States, and Canada came to crossing the red line that restrained chemical weapon use during World War II. Unlike World War I, belligerents did not release poison gas regularly during the Second World War. Yet, the looming threat of chemical warfare significantly affected the actions and attitudes of these three nations as they prepared their populations for war, mediated their diplomatic and military alliances, and attempted to defend their national identities and sovereignty.

The story of chemical weapons and World War II begins in the interwar period as governments and…


Book cover of Song of the Paddle: An Illustrated Guide to Wilderness Camping

Ernest Herndon Author Of Paddleways of Mississippi: Rivers and People of the Magnolia State

From my list on adventures on the water.

Why am I passionate about this?

As a longtime outdoors editor of a Mississippi newspaper, I actually got paid to paddle local rivers. Over the decades, I expanded my territory to adjacent states, the South, the continent, and other countries. I parlayed my experiences into several books on rivers. As a paddler and writer, I naturally love to read about adventures on the water–not only classics like Mark Twain's Life on the Mississippi River and Paul Theroux's Happy Isles of Oceania but also the many less-known but highly praiseworthy books like those listed here.

Ernest's book list on adventures on the water

Ernest Herndon Why Ernest loves this book

Bill Mason was a legend in the world of paddling. He was old-school: red and black plaid wool shirt, wood-and-canvas canoe, canvas lean-to-style tent. His sojourns in the North Woods inspired me in my own explorations of the Deep South. When he paddled Lake Superior, I thought of Louisiana's Atchafalaya Swamp. When he canoed the Hood River, I thought of Mississippi's Pascagoula.

This book combines in-depth advice on wilderness travel with accounts of some of Bill's own journeys. He was also an artist and filmmaker. His documentary, Waterwalker, is a must-see classic for anyone who loves adventure on the water. 

By Bill Mason ,

Why should I read it?

1 author picked Song of the Paddle as one of their favorite books, and they share why you should read it.

What is this book about?

The return of a classic paddling guide.

More than a how-to camping and paddling guide, Song of the Paddle is a philosophical guide to outdoor living. Written by the acclaimed paddler and outdoorsman, Bill Mason, the book leads readers on a journey of exploration and discovery.

Mason writes from an intensely subjective viewpoint and the advice is practical and sound. He emphasizes the difference in perception between camping (rough) and outdoor living (comfort). Each page is packed with hard-won tips and tricks for enjoying the great outdoors. No detail is ignored -- from keeping campfire smoke out of your eyes…

Book cover of Search Out the Land: The Jews and the Growth of Equality in British Colonial America, 1740-1867

David S. Koffman Author Of No Better Home?: Jews, Canada, and the Sense of Belonging

From my list on Canadian Jewish life.

Why am I passionate about this?

I was born and raised as both an anglophone Canadian and a diaspora Jew. After living in Montreal, Jerusalem, and New York for a total of about 15 years, I returned to my hometown of Toronto and took up the position of the J. Richard Shiff Chair for the Study of Canadian Jewry at York University, where I work as a professor of history. I teach undergraduate students, graduate students, fellow academics, community leaders, and the wide public about all sorts of dimensions of this very religiously diverse, culturally diverse, socio-economically diverse, and politically diverse community of 400,000+ souls, with its 260+-year-old history. 

David's book list on Canadian Jewish life

David S. Koffman Why David loves this book

I love this book’s choc-a-block presentation of actual archival fragments from Jewish life in the British colonies that would eventually become Canada.

I also like that the book’s husband-wife, antiquarian, author team aimed to fuse together two objectives in one book: on the one hand, to paint a relatable picture of what Jewish life looked like during this period when Upper Canada was still being formed, and on the other hand, to account for the step-by-step process of Jews gaining civil rights in the new world.

When I teach Canadian Jewish history, I not only read this book with my students but also bring them into the archives that contain Godfrey’s trove of archival fragments of early Jewish Canadiana, which they collected before and while writing the book.

What is this book about?

Mapping the history of Canadian Jews from the arrival of the first settlers before 1750 through to the 1860s, Search Out the Land introduces a new set of colourful players on Canada's stage. Ezekiel Solomons, John Franks, Jacob Franks, Chapman Abraham, Rachel Myers, Moses David, Samuel Hart, Elizabeth Lyons, and a host of others now take their appropriate place in Canadian history. Focusing on the significant role played by Jews in British North America in the fight for civil and political rights, the authors compare the development of Canadians' rights with that in other British jurisdictions of the time and…


Book cover of The Fourth World: An Indian Reality

Radhika Natarajan Author Of Hear Our Voices: A Powerful Retelling of the British Empire Through 20 True Stories

From my list on why imperial history matters today.

Why am I passionate about this?

I first became interested in the history of the British Empire as an undergraduate. Understanding this history helped me relate my parents’ experiences growing up in a postcolonial nation with the history of the United States, where I grew up. As an academic historian, my research and teaching emphasize connections—between disparate places, between the past and present, and between our personal experiences and those of people born in distant times and places. My first children’s book allowed me to translate my scholarly work for a young audience. I hope this list of books that inspire my approach to history encourages your own investigations of imperialism and its pasts!

Radhika's book list on why imperial history matters today

Radhika Natarajan Why Radhika loves this book

George Manuel was once asked by a white coworker, “Does Indians have feelings?” Refusing dehumanization, Manuel reveals the ongoing colonial relations between First Nations and the Canadian settler state. He charts his political journey from Secwepemcúl̓ecw to the National Indian Brotherhood to the World Council of Indigenous Peoples.

Manuel argues that the victories of the anti-colonial independence movements of the twentieth century did not end colonial domination of Indigenous Peoples—what he calls the Fourth World. The Fourth World is not a destination but the right to travel on your own road in your own way.

With a new insightful introduction, foreword, and afterword, the book's latest edition shows how Manuel’s analysis of colonialism and vision for solidarity continue to be relevant to contemporary struggles for decolonization.

What is this book about?

A foundational work of radical anticolonialism, back in print


Originally published in 1974, The Fourth World is a critical work of Indigenous political activism that has long been out of print. George Manuel, a leader in the North American Indian movement at that time, with coauthor journalist Michael Posluns, presents a rich historical document that traces the struggle for Indigenous survival as a nation, a culture, and a reality. The authors shed light on alternatives for coexistence that would take place in the Fourth World-an alternative to the new world, the old world, and the Third World. Manuel was the…

Miranda Rijks Author Of Violets Are Blue

From my list on twisty psychological thrillers about creepy neighbours.

Why am I passionate about this?

I’m the author of 26 twisty psychological thrillers, many of which are Amazon bestsellers. I’ve sold over three-quarters of a million books and particularly enjoy writing about dysfunctional families and unpleasant neighbours! Several of my novels touch upon this theme: The Visitors, The New Neighbour, and Violets Are Blue, to name just three. And yes, I have drawn upon some difficult experiences I’ve had with neighbours... I’m a full-time author and I’m also an avid reader of thrillers and enjoy nothing more than reading a book with an ending that makes me gasp!

Miranda's book list on twisty psychological thrillers about creepy neighbours

Miranda Rijks Why Miranda loves this book

From the very first page, Someone Like You had me hooked.

This is one of those books you pick up “just to start” and before you know it, hours have disappeared because you simply can’t put it down. It’s full of interesting characters and plot twists and left me feeling on edge, with my heart racing as I turned those pages faster and faster. 

I loved the setting with its super creepy vibes, which only increased exponentially when more and more scary things started happening. I really warmed to Carey and her son and was rooting for them throughout. The explanations at the end made complete sense and tied things up perfectly.

I thought this was an excellent debut novel and I look forward to reading more by Elena Frost.

Book cover of Encampment

Richard Harrison Author Of My Mother Joins the Resistance

From my list on answering sorrow with understanding.

Why am I passionate about this?

I started to write poetry because I loved the poetry my father recited. I've kept writing poems because poems brought me closest to the mystery my father and mother were to me. Both my parents lived through the Depression in England and the Second World War that followed. Both of them suffered, one as a civilian casualty, the other as a soldier, and both carried to their deathbeds the things they did and the things that were done to them. The books that move me most offer me the words that lift the weight of sorrow and the understanding that replaces grief and anger with compassion.

Richard's book list on answering sorrow with understanding

Richard Harrison Why Richard loves this book

My son works with the unhoused in our city.

This is a book about extreme compassion, and the long and torturous work of it in the face of neighbourhood fear and municipal hostility towards those who live without fixed addresses and all that that entails. 

Further, I see in Encampment the hope that on a personal and social level, we all have it within us to understand people we didn't think we could and keep alive the capacity we're born with to love those whom so many tell us we should not.
