Book cover of The Keeper of Lost Causes: The First Department Q Novel

Jo Jakeman Author Of The Vanishing Act

From my list on books with the allure of a cold case.

Why am I passionate about this?

It’s hard to pinpoint where my interest in cold cases began, but I remember reading about the Isdal Woman and being intrigued. She was found in Norway in 1970, badly burned, with the labels cut off her clothes. Police discovered fake identities and disguises in suitcases left at the railway station, but, to this day, have no idea who she was. I’m a member of several Facebook groups where people investigate cold cases, and I’m always amazed at how these clues can be put together so many years later. Or, in some cases, how some people go unnamed, or crimes unsolved despite all the resources at our fingertips.

Jo's book list on books with the allure of a cold case

Jo Jakeman Why Jo loves this book

I have to confess that I discovered these books after watching the TV series Department Q. As soon as I saw "Based on the books by Jussi Adler-Olsen," I knew I had to read them.

The books differ significantly from the TV show. For one thing, they are set in Copenhagen, not Scotland. But the dark humour and clever plots are still the same. In this, the first of the series, Carl Morck—who is recovering from an incident where two of his colleagues were shot—is made the head of Department Q, looking into cold cases.

His first case is the disappearance of a politician who we know is still alive, but no one—apart from Morck—is looking for him anymore, assuming he fell off a ferry.

What is this book about?

Get to know the detective in charge of Copenhagen's coldest cases in the first electrifying Department Q mystery from New York Times bestselling author Jussi Adler-Olsen.

Carl Morck used to be one of Denmark's best homicide detectives. Then a hail of bullets destroyed the lives of two fellow cops, and Carl-who didn't draw his weapon-blames himself. So a promotion is the last thing he expects. But Department Q is a department of one, and Carl's got only a stack of cold cases for company. His colleagues snicker, but Carl may have the last laugh, because one file keeps nagging at…

Book cover of Listen for the Lie

Nicola Sanders Author Of Don't Believe Her

From my list on gaslighting by the people you love most.

Why am I passionate about this?

I write psychological thrillers, and I find stories where the main character thinks they’re going crazy, particularly gripping, especially when it’s caused by (supposed) loved ones. I suspect it’s because these stories share an element of "this could happen to me." I’ve only written three books, but I’d say all of them have an element of gaslighting, probably because I sit down and think things like, What would it feel like if your best friend came back after many years, and you’re the only one who can tell it’s not her? It’s a deliciously creepy way to pass the time.

Jo Jakeman Why Jo loves this book

I read this while recuperating from an operation, and it was the pick-me-up I needed.

What starts off as a current missing person’s case becomes an investigation into a cold case as it comes to light that the two cases could be linked. The sleuths in this case are retired spies, The Martini Club, and they are such a fun group of characters. It’s the second book of Tess Gerritsen’s to feature this cast of characters, and they have skills to outdo the local police chief, Jo—and occasionally get in her way.

Book cover of Truly Devious

Elisabeth Wathen Author Of Glorious Debris

From my list on loving character development as much as getting a new mystery every time.

Why am I passionate about this?

Mysteries are fun to write, but it’s never just the central mystery that interests me. I want the relationships, the people, sometimes even the place to fill my books with their own smaller puzzles and hidden truths. I have long believed that all novels are, in fact, mysteries: if you’re not wondering what will happen next, or where the truth lies, why bother? The suspense of wondering what a character will do next, or what past experience has led to an aspect of their personality, is at least as important as who committed the murder. I hope that my readers will feel the same.

Elisabeth's book list on loving character development as much as getting a new mystery every time

Elisabeth Wathen Why Elisabeth loves this book

Though marketed for a YA audience, this book easily crosses over to appeal to all readers, as long as they love a good mystery and some quality character growth.

Main character Stevie Bell loves true crime, and she makes it clear right from the start that she’s not interested in wasting her time with much else. Something of a misfit with a healthy dose of impostor’s syndrome, she’s got something to prove and plenty of stumbling blocks that get in the way. But she is fiercely devoted to finding answers, even to the point of recklessness.

Hints at future romance—never her priority, yet persistently unavoidable—along with her passion, intelligence, and disregard for the rules make her a heroine you can happily follow through several books.

Book cover of Something Happened

Why am I passionate about this?

I consider myself a disruptor of sorts, both in my life and in the art I make (I’m an actor, too). So I am by nature drawn to novels that bend and reshape (and sometimes ignore altogether) the rules and conventions that are supposed to govern the novelist’s craft and lead me to experience the world—and often the art of writing fiction itself—in ways I have never experienced either before. The novels on my list do just that.

Steve's book list on four literary novels that break the traditional rules of novel writing and one terrific thriller

Steve Schlam Why Steve loves this book

I studied with Joe Heller at City College in New York, earned my MA in Creative Writing under his tutelage.

Catch-22 is his most well-known and celebrated work, of course; nevertheless, I consider his second novel, Something Happened, his deeply unsettling portrait of Bob Slocum, a mid-level executive in a disintegrating marriage and estranged from his children who is navigating the minefield of his corporate life, and the devastating anxiety, soul-numbing alienation and paralyzing dread his journey produces that bears fruit at last in the tragedy he has expected and feared and sought desperately to avoid for so long, to be his true masterpiece.

It provided me with an essential lesson in the use of narrative tension to engage readers on a deeper, more subliminal level and keep them engaged until the very last word.

Structurally, stylistically, even thematically, echoes of Something Happened permeate my own novel: the often…

What is this book about?

Bob Slocum was a promising executive. He had an attractive wife, three children, a nice house, and as many mistresses as he desired. His life was settled and ordered; he had conformed and society demanded he be happy - or at least pretend to be, But the pretence was becoming more and more difficult, as Slocum's discontent grew into an overwhelming sense of desolation, frustration and fear. And then something happened. . .

Book cover of On Wilder Seas: The Woman on the Golden Hind

G.J. Williams Author Of The Conjuror's Apprentice

From my list on tempestuous times and crimes of the Tudors.

Why am I passionate about this?

I studied the Tudor era in high school and have been hooked ever since. It was an era of enormous change. The world was opening up, science was advancing, religion was losing its grip over people, and new ideas were challenging every level of society. Discovery was everywhere–new planets, lands, theories, foods, and trading routes. Society was changing, and women were beginning to have a voice and education. It was also an era of characters–men and some women who made a mark on the world through their wit and wisdom–and some just by being rogues. There are no dull moments in Tudor times.

Book cover of Can You Sue Your Parents for Malpractice?

Ned Lecic Author Of The Law is (Not) for Kids: A Legal Rights Guide for Canadian Children and Teens

From my list on demonstrating that children are people too.

Why am I passionate about this?

I have a deep-set interest in and passion for human and civil rights, particularly children’s rights. I see the law, with which I have had a fascination since the age of 14, as the primary vehicle for advancing those rights. My research on the law has always been on my own, and apart from several legally themed high school and university courses, I am a layman in this field. Nonetheless, I have extensively studied law privately for many years, with a particular focus on how it affects relations among people, including those between children and adults. Activism for social change is one of my primary motivators in life, my main purpose and direction, and my reason for being. 

Ned's book list on demonstrating that children are people too

Ned Lecic Why Ned loves this book

I love this classic novel; it is one of my old favorites.

Nowhere in the genre of young adult literature does there seem to be an author more subversive than Paula Danziger; here (and in the companion novel The Cat Ate My Gymsuit), she directly encourages the young reader to question adult authority and suggests that with protests and education about what rights the law gives (and withholds from) young people, it might be possible to effect change and increase their rights.

I also found it great that the novel shows the protagonist’s parents in raw realism–the father as a hypocritical, cheap, unlikable domestic despot, the mother as a shrinking violet who at first tends to excuse the father and conform to his expectations, but eventually starts questioning her stance when she sees her daughters rebel.

Book cover of The Bangalore Detectives Club

Jinny Alexander Author Of Claude, Gord, Alice, and Maud

From my list on an unusual take on traditional cozy mystery.

Why am I passionate about this?

I’ve always adored mysteries. My dad has the entire collection of Agatha Christie books, but even before I read those, I worked through his ancient original hardbacks of Enid Blyton's Famous Five books and the less well-known Malcolm Saville Lone Pine series. I love getting totally engrossed in a series, so I really get to BE the main character–I am one of four siblings, and when I wasn’t too busy reading, we were the Famous Five. I was George. I think I still am, to be perfectly honest–she was fiery, passionate, loved her dog, and wanted to serve justice and out the bad guys. What a role model!

Jinny's book list on an unusual take on traditional cozy mystery

Jinny Alexander Why Jinny loves this book

A year or so ago, I read a lot of factual books about India, so I was delighted to find this Golden Age cozy mystery set in a land I was falling in love with through books. This book took me back to a pre-partition India still under British rule, with a realistic glimpse of life under colonialism alongside a hefty–hopefully less realistic–dose of murder and mystery.

I adored how Harini Nagendra created a strong, independent female character who still feels genuine and believable in the time and place in which the book is set–a time when most women were stifled, submissive, and governed by their husbands–and how the observations of colonization feel true to life while remaining both sympathetic and observant to the Indian culture and ways of life.

The setting is vividly portrayed, and the sights and sounds of 1920s India are an absolute delight. The main characters…

Brent C. Lambert Author Of A Necessary Chaos

From my list on fantasy happening in modern-inspired worlds.

Why am I passionate about this?

Worldbuilding is something I absolutely adore, and I have always wanted to see more fantasy in worlds created around a more modern thought process. Worlds that got away from the medieval and instead found inspiration in places like 1920s America or 1950s Mexico or anywhere with cars and motorcycles existing right alongside dragons. It’s what I try to write and its desperately what I want to read. Fantasy has so much more range than I think it is given credit for.

Brent C. Lambert Why Brent loves this book

This book has one of the most refreshing and terrifying take on the concept of immortality that I’ve ever seen. I love it because of how it tackles policing, what it means to be a decent person, and how power unchecked will inevitably consume all it touches. Also, it’s extremely queer, and the prickly immortals were just too hard not to fall in love with.
