I’ve finally read my first Sarah Pinborough thriller, and it absolutely won’t be my last. INSOMNIA—available today in the US—is one of the most genuinely unsettling and utterly gripping psychological thrillers I’ve read in ages, and it’s sure to be one of my favorite books of 2022. In this twisty, paranoia-inducing tale, a woman anxiously awaits her 40th birthday—but not for the reason you might think. When Emma’s mother turned 40, she lost her mind…and now, as Emma’s own 40th birthday approaches, she begins to fear the very same thing might be happening to her. INSOMNIA is an “unreliable narrator” thriller done right—Pinborough expertly draws readers into Emma’s increasingly terrifying world, where no one and nothing can be trusted, not even Emma’s own mind. This book will keep you on your toes, never quite sure who to trust, and who might be hiding dark secrets. INSOMNIA is a story about what we inherit from our family, and the pieces of those inheritances that we wish we could escape. It’s also one of the most downright entertaining thrillers I’ve read in ages. Clear your schedule and—cheesy as it may be to say, it’s true—prepare to lose sleep over INSOMNIA.
