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…

Jo Jakeman Why Jo loves this book

A small town bursting with secrets? A loner protagonist who is smart and funny, with a lot to prove? Where do I sign up?

Frankie Elkin is on a one-woman mission to find missing people that everyone else has given up on. She goes to Boston to look for a missing teenager but encounters a fair amount of resistance when she starts asking questions.

This book has a lot of heart and is one of those that demands to be read in one sitting.

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.

Lucy's best friend Savannah was murdered, and Lucy is suspected of having killed her. But Lucy can't remember anything about that night. Convenient? Plenty of people think so, including those closest to her. Is Lucy doing the gaslighting?

This plot is masterfully constructed, and I can’t say much more without spoilers. I loved it, and the gaslighting is out of this world.

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 The Slide Area

Laurence Klavan Author Of The Cutting Room

From my list on Hollywood murder, crime, and failure.

Why am I passionate about this?

As a child, finding reality both overwhelming and boring, I was drawn to movies. My father, a New York City disc jockey also at odds with reality, had contacts at a sixteen-millimeter movie rental company. He often brought films home, shown in a makeshift screening room he set up in our basement. Singin’ in the Rain, the classic musical, made a great impression there. Its funny first scene at a movie premiere featured a pompous star’s ennobling account of his early days, comically contradicted by the tacky, scrounging, painfully undignified truth. What lay behind Hollywood's glamor, smiles, and success soon became as interesting to me as what was on the screen.

Laurence's book list on Hollywood murder, crime, and failure

Laurence Klavan Why Laurence loves this book

Gavin Lambert adapted the works of D. H. Lawrence and Tennessee Williams for the films Sons and Lovers and The Roman Spring of Mrs. Stone. He directed one interesting, low-budget, Paul Bowles-like movie, Another Sky. His prose work is insightful about the behind-the-scenes world of the movies.

The linked stories in this book memorably spotlight hangers-on and working-class people on the edges of entertainment. Also of interest is Inside Daisy Clover, his novel about a teen tomboy star which became an affected, bombastic, entertaining Natalie Wood movie.

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

What is this book about?

The land along Pacific Palisades is apt to slip away without warning, hence the road-side signs - SLIDE AREA. Narrated by a script-writer, Lambert's widely-acclaimed 1959 Hollywood classic of lonely souls marooned on a glittering wasteland is a perceptive and sensitive study of human emotion.


Book cover of What You Wish For

Joy Jarrett Author Of Curse of the Orkney Sea

From my list on islands as a setting.

Why am I passionate about this?

As a child, I received an electronic typewriter as a gift and immediately got to work on a story about a family living on an island. Even at ten, I recognized the power of islands, with their built-in problems of isolation and rich possibilities for metaphors. So it only made sense I’d one day publish a book set on one. If you’re like me and can’t resist books with island settings, you’ll love these book recommendations. Each island in this collection has its own personality that becomes a character of its own, and none of these books could exist in the same way without their unique settings. 

Joy's book list on islands as a setting

Joy Jarrett Why Joy loves this book

I’m a school librarian, so I couldn’t pass up a book about a librarian who works in an island school! This is set on Galveston Island, and the Texas culture there definitely brings its own flavor to the story.

The friendly community feel of the school and town really appealed to me and gave this book a cozy dimension despite its darker themes. A new principal arrives and immediately begins ruining the happy librarian’s life with new rules that she fights at every step—so naturally, the two begin to fall in love. I loved the animals in this book. I couldn’t stop smiling when I finished this one.

Book cover of The Girl with No Face

Alice Poon Author Of The Heavenly Sword

From my list on wuxia/xianxia fantasy books with strong-willed and free-spirited female leads.

Why am I passionate about this?

My passion for Chinese history took root when I began reading Jin Yong’s wuxia novels, which are all steeped in Chinese historical background. My fiction writing career began with historical fiction based on Chinese history. Through my earlier research work, I discovered that Chinese historians have always given short shrift to the influence of women on cultural, political, and social developments throughout the ages. That led me to decide to center my writing around inspiring Chinese female historical figures. After publishing The Green Phoenix and Tales of Ming Courtesans, I branched out to write wuxia fantasy novels, but with the same objective of featuring admirable female historical/fictional characters.

Alice's book list on wuxia/xianxia fantasy books with strong-willed and free-spirited female leads

Alice Poon Why Alice loves this book

I’m most impressed by the fact that the author, a white American, did meticulous research into Chinese mythology and Daoist practices. The kungfu fight scenes are also arresting.   

Xian Li-Lin, a plucky Daoist priestess with superior martial arts skills who is bent on forging her own way in a male-dominated world of 19th century San Francisco Chinatown, charmed me from the start of the novel (which is a sequel but can be read as a standalone). Beset with personal challenges as a lonely Chinese widow with a harsh father, she still takes it upon herself to fend helpless immigrants from the perils of ghosts, evil spirits, and gangsters.

The adventures of Li-lin, a Daoist priestess with the unique ability to see the spirit world, continue in the thrilling follow-up to the critically-acclaimed historical urban fantasy The Girl with Ghost Eyes.

It's the end of the Nineteenth Century. San Francisco's cobblestone streets are haunted, but Chinatown has an unlikely protector in a young Daoist priestess named Li-lin. Using only her martial arts training, spiritual magic, a sword made from peachwood, and the walking, talking spirit of a human eye, Li-lin stands alone to defend her immigrant…


Book cover of Sleeping Murder

KJ Sweeney Author Of The Body at Back Beach

From my list on adventures of female amateur sleuths.

Why am I passionate about this?

I’ve loved murder mysteries since I first discovered the genre. As a child, I loved watching Morse, Miss Marple, and other detectives as they got to the bottom of whodunit. I was hooked. It wasn’t long before I started to read books starring these detectives. I really love the way that female amateur detectives often have far more ideas of what’s going on and why things have happened than the men who populate the books. What woman can’t resist reading about another woman who just gets to the bottom of it all? I know I can’t, but these books are some of the very best in the genre.

KJ's book list on adventures of female amateur sleuths

KJ Sweeney Why KJ loves this book

My all-time favorite amateur detective is Miss Marple, and if I had to pick a favorite book she is in, it would be this one. I love the idea of a quiet, mostly ignored spinster who most people dismiss being the one character who seems to know exactly what is going on and what people are up to.

I really like the way Miss Marple figures out why the main character thinks she is going mad and proves that she isn’t. In this book, Miss Marple really proves her status as one of the best amateur detectives, and I love it.

Tash McAdam Author Of No One Left But You

From my list on queer young adult books that will keep you guessing.

Why am I passionate about this?

I’m autistic, with a passion for narrative structure and my brain is exceptional at predicting twists, so something genuinely surprising is a rare treat I crave and value. As a queer and trans person, I’m always looking for content in which I can see myself and my loved ones. I’m obsessed with YA thrillers that don’t just keep me guessing but also give me messy, brilliant, unforgettable queer characters to root for. These are the books that stuck with me, made me lose sleep to finish, and gave me new queer icons to love. I hope you enjoy them as much as I did!

Tash McAdam Why Tash loves this book

I’m an absolute sucker for a ‘what really happened that night’ tale and this is one of my all time favourites due to the unreliable narration and the sense of slowly creeping dread.

The core of this book is the messy tangle of friendship, obsession, and unspoken longing, which I can never get enough of. Throughout my first read of the story, I re-evaluated what I thought I knew, and went back to the start over and over. I had to know who was lying…

J.D. Blackrose Author Of Demon Kissed

From my list on Great romantasy books that aren’t by Sarah J. Maas.

Why am I passionate about this?

I’m passionate about this because I write romantasy too, and so do many other wonderful authors. Sarah J. Maas is a legend in the Romantasy genre, and she’s prolific, so there’s a lot to read with her various series. But, if you’ve finished with her books and are looking for more, there are plenty of authors out there doing amazing, spine-tingling, dare I say loin-tingling work, and we should celebrate them. Besides, no matter how prolific Ms. Maas is, readers will always finish books faster than even she can write them.

J.D.'s book list on Great romantasy books that aren’t by Sarah J. Maas

J.D. Blackrose Why J.D. loves this book

I loved the main character, the beautifully named Saffron Everleigh. She’s a woman in 1923 London, trying to make her way in academia at a time when women weren’t usually allowed in the doors.

Her scientific interests and studies in botany come in handy when she attends a dinner party for the school, and a professor’s wife drops to the floor, poisoned by an unknown substance. Working with the equally passionate, ahem, Alexander Ashton, a fellow researcher, Saffron must investigate the murder or wind up next on the murderer's list. There are two more books in this series, so we are lucky to spend more time with our plucky heroine.
