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.

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 ,

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.

In the turquoise waters of the Caribbean, something lethal is on the move.

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 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.

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

From my list on the War of 1812 and Canadian sacrifice for freedom.

Why am I passionate about this?

I served for 40 years in the British Army, including many tours of active duty. I commanded operations in every rank, from Second Lieutenant to Lieutenant General. I had the privilege of commanding not only British troops, but also troops from the USA, Canada, Australia, and more. I was Director-General and Master of the Royal Armouries and since 2013 I have been Visiting Professor in War Studies at King’s College London. I hold three degrees including a PhD. I've published more than 20 books and numerous articles. I continue to learn new things from history every day, as well as passing on our history to others, and that’s what books are all about.

Jonathon Riley Why Jonathon loves this book

Readers are Dianne and her husband Don have been personal friends for many years. Like many people, I was deeply saddened by her untimely death last year. Dianne had a wonderfully fluent written style, so easy to read, and could capture a moment like few others. Her book gives insights into wartime life and the role of women in the early 19th Century in Quebec, Montreal, and Toronto (the York), as well as in Washington DC and Philadelphia. While the men did the fighting, the women backed them up – on the frontier, quite literally. A fascinating book written with passion and insight.

What is this book about?

The War of 1812 between the United States and Britain has been covered in detail by many historians, but its impact on the lives of women has been largely overlooked. After years of research, Dianne Graves has produced a marvelous study of how the war affected women at all levels of society, from high society in Washington and Quebec to the women who followed their husbands to the front lines. She brings to life the untold stories of wives, daughters, heroines and harridans, as revealed in memoirs, diaries and letters of the time. The book is well illustrated with portraits,…

Valerie's book list on capturing Canada’s colourful immigration history

Valerie Knowles Why Valerie loves this book

Canadian immigration policy has always been a subject of fierce political and public debate and in this authoritative work Ninette Kelley and Michael Trebilcock examine the interests, ideas, institutions, and rhetoric that have shaped it. The authors begin their study in the pre-Confederation period and interpret major developments in the evolution of Canadian immigration policy. Among the shameful episodes they describe are the deportations of the First World War and Great Depression and the uprooting and internment of Japanese Canadians after Pearl Harbour.

In this second edition of the widely recognized and authoritative work The Making of the Mosaic, Ninette Kelley and Michael Trebilcock have thoroughly revised and updated their examination of the ideas, interests, institutions, and rhetoric that have shaped Canada's immigration history.

Book cover of The Home for Unwanted Girls

Vered Hazanchuk Author Of Life As An Almost

From my list on to make you wish you joined that book club.

Why am I passionate about this?

I love book club. If I could make it a requirement for everyone in the universe to give it a try, I would. I was an English major in college, so that feeling of ending an amazing story and needing someone to discuss it with never fully went away. All book club books should be thought-provoking, but the best add that intricate and wholehearted understanding, I think, that only literature can. Why do the characters you least understood or felt a kinship with suddenly have your heart, what do they want, need, feel, think? I hope these novels help you better understand. The who and what are beside the point.

Vered Hazanchuk Why Vered loves this book

I think I’ll be recommending this book to people until the end of time. It’s just so, so good.

What I love most about it is it brings a forgotten part of history to life: a time when orphanages in 1950s Quebec misdiagnosed children as mentally ill to qualify for the better funding allocated to psychiatric hospitals. An obscure moment in history, generations of family scandals and secrets, and a forbidden love story? Yes, please.

By Joanna Goodman ,

Why should I read it?

1 author picked The Home for Unwanted Girls as one of their favorite books, and they share why you should read it.

What is this book about?

Philomena meets Orphan Train in this suspenseful, provocative novel filled with love, secrets, and deceit—the story of a young unwed mother who is forcibly separated from her daughter at birth and the lengths to which they go to find each other.

In 1950s Quebec, French and English tolerate each other with precarious civility—much like Maggie Hughes’ parents. Maggie’s English-speaking father has ambitions for his daughter that don’t include marriage to the poor French boy on the next farm over. But Maggie’s heart is captured by Gabriel Phénix. When she becomes pregnant at fifteen, her parents force her to give baby…


Book cover of The Wings of Night

Mark Lisac Author Of Where the Bodies Lie

From my list on novels depicting regions of Canada.

Why am I passionate about this?

I’ve been a writer most of my life, moving from high-school essays to working for newspapers to creating novels. One way or another, I’ve also spent much of that time exploring Canada's back roads and smaller communities. Those places and the people living in them have a pungent reality that I often find missing in the froth of modern urban society. The places and their people are interesting and inspiring, and I always get drawn back to reading and writing about them.

Mark Lisac Why Mark loves this book

I was very much taken with this novel’s blend of romance, mystery, and exploration of whether you can ever go home again. Raddall doesn’t get much mention and is largely remembered for his other novels when he does. That’s a shame.

This 1956 work stands up very well against more recent works. It features unadorned yet persuasive prose that many modern writers can only wish for. Raddall quite evidently intended it as a loving, almost lyrical, description of rural Nova Scotia. He succeeded.

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

What is this book about?

It was spring in Nova Scotia when Neil Jamieson returned to Oak Falls. Wild and resentful, he had run away fourteen years before. Now, still blustering and belligerent, educated but not subdued, he took a fresh look at the citizens of Oak Falls and particularly at the timber town's decaying sawdust aristocracy.


Book cover of The Trudeau Formula: Seduction and Betrayal in an Age of Discontent

Jeremy Appel Author Of Kenneyism: Jason Kenney's Pursuit of Power

From my list on understanding the political moment we’re in.

Why am I passionate about this?

I’m a journalist in Edmonton, Canada, who covered former premier Jason Kenney’s rise through Alberta politics, in which he tapped into the populist zeitgeist of Donald Trump and Brexit, and his eventual implosion. I have a newsletter on Substack, "The Orchard," where I cover the intersection of politics, the media, and corporate power. Through my journalism, I’ve developed a keen interest in this age of mass discontent we find ourselves in, with right-wing political and economic elites promising to blow up the entire system they embody while feckless liberal politicians seek to tinker around the edges to make the established order more palatable. 

Jeremy's book list on understanding the political moment we’re in

Jeremy Appel Why Jeremy loves this book

I regard Canadian Prime Minister Justin Trudeau as the embodiment of an empty progressive politics that is far more concerned with style over substance.

Martin Lukacs does a great job in The Trudeau Formula of outlining how Trudeau’s combination of soaring rhetoric and tepid reform on issues like economic inequality, Indigenous reconciliation, and the climate crisis works to stave off the more systemic changes needed to address these concerns in a substantive way.

Lukacs aptly demonstrates how Trudeau serves to uphold the status quo while presenting himself as an agent of transformative change. 

By Martin Lukacs ,

Why should I read it?

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

What is this book about?

"The book is not a biography of Justin Trudeau, nor is it a treatment of the minutiae and manoeuvres of party politics. It is an investigation into how the Liberal government governs in the shadow of a silent, multi-decade corporate coup in Ottawa that dares not speak its name. It tells the hidden history of how the Liberal party has served as the most effective vehicle for implementing deeply unpopular neoliberal policies--and how Justin Trudeau continues this agenda today."--

Mark Lisac Why Mark loves this book

I loved this book because I loved the characters. Richards invested them with dignity even when they were flawed or endlessly frustrated by fate. They can go through life largely unnoticed except by their closest acquaintances and relatives. But they offer hope despite their failures and tragedies.

This was the first novel in Richards’ Miramichi Trilogy. It and the two subsequent novels, plus much of Richards’ later work, create a strong sense of the province of New Brunswick, even when the characters have a universal quality.
