"An extraordinary novel of psychological suspense that is more wicked than Marwood's Edgar-winning Wicked Girls and darker than her Macavity-winning The Killer Next Door." -Booklist, *starred review*

"Intelligently assimilated research, a slow build with a growing sense of unease and a chillingly believable plotline add up to the best sort of dark psychological thriller."--The Guardian

"An Edgar winner for her The Wicked Girls, Marwood again shows a mastery at creating new worlds."--Oline H. Cogdill, Associated Press

"Marwood's novels offer superbly executed masterclasses in compelling and stupendously creepy mysteries."--CrimeReads

"I devoured The Poison Garden . . . Gripping and utterly convincing, it's Alex Marwood at the top of her (already impressive) game"--Jojo Moyes, #1 New York Times bestelling author of Me Before You

"God, Alex Marwood is good. Like all her books, The Poison Garden is absolutely, beautifully realized, full of wry, defiant humor and pitch-black, hand-over-your-mouth suspense. I'd read her grocery lists."--Flynn Berry, author of Under the Harrrow

"Highly imaginative, yet consistently believable, this wonderful dystopian novel is both terrifying and unsettling as if a harbinger for our times. A well written and thrilling read." -Lisa Ballantyne, internationally bestelling author of The Guilty One

"A gripping, unexpected novel with graphic elements that are not for the faint of heart."--Kirkus

"Cults have long captured the popular imagination. We're repelled yet fascinated, disturbed yet wildly curious. Alex Marwood's fourth thriller, The Poison Garden, will slake readers' thirst for stories about what goes on in such communities and what happens when everything falls apart." -BookPage

Praise for The Wicked Girls

"The suspense keeps the pages flying, but what sets this one apart is the palpable sense of onrushing doom." -Stephen King

"Harrowing." -Marilyn Stasio, The New York Times Book Review

Praise for The Killer Next Door

"If you read Alex Marwood's The Wicked Girls, her new one--The Killer Next Door--is even better. Scary as hell. Great characters." -Stephen King

"With her sophomore outing, Marwood has turned out not just a spooky, blood-and-guts thriller, but a cannily observant novel that explores social fissures while delivering a modicum of hope." -The Boston Globe

More praise for The Darkest Secret

"This third novel from one of psychological suspense's best writers confirms Marwood's first hat trick." -The Boston Globe (Best Books of 2016)

"Brilliant." -The Atlantic

"[Marwood] demonstrates, without a doubt, that she is one of crime fiction's brightest stars."-Megan Abbott
