For readers of Gillian Flynn and A. J. Finn comes the thriller of the year: the dark and twisty tale of a young woman who commits murder with her eyes wide open and her brain still asleep.

THE WORLD WILL KNOW HER NAME

What if your nightmares weren’t really nightmares at all?

We spend an average of thirty-three years of our lives asleep. But what really happens, and what are we capable of, when we are sleeping?

Anna Ogilvy was a budding twenty-five-year-old writer with a bright future. Then, one night, she stabbed two people to death with no apparent motive—and she hasn’t woken up since. Dubbed “Sleeping Beauty” by the tabloids, Anna suffers from a rare psychosomatic disorder known to neurologists as “resignation syndrome.”

Dr. Benedict Prince is a forensic psychologist and an expert in the field of sleep-related homicides. His methods represent the last possible hope of solving the infamous “Anna O” case by waking Anna up so she can stand trial. But the doctor must be careful treating such a high-profile suspect—he’s got career secrets and a complicated personal life of his own.

As Anna shows the first signs of stirring, Benedict knows he must determine what really happened and whether Anna should be held responsible for her crimes.

Only Anna knows the truth about that night, but only Benedict knows how to discover it. And they’re both in danger from what they will discover.

"An irresistible concept beautifully executed - certain to be one of the year's best thrillers."  — Lee Child, #1 New York Times bestselling author of the Jack Reacher series 

“A wickedly stunning work. Blake’s experience as a screenwriter is on full display here as he ramps up the suspense and carves out his cast of wonderful characters with the skill of a real pro. The twist is one of the best I’ve read and ranks right up there with The Silent Patient. Sure to be wildly popular and to have fans clamoring for Blake’s next work.” — David Baldacci, international bestselling author of the Amos Decker series

"A riveting, unsettling crime novel that will keep you turning pages well past your bedtime. Is Anna O a sleeping beauty or a sleeping killer? Matthew Blake's tension-filled thriller is as elusive and mysterious as sleep itself."  — Nita Prose, #1 New York Times bestselling author of The Maid and The Mystery Guest

“Anna O sits at the pinnacle of psychological suspense! It’s a nonstop thrill ride through the darker sides of the human mind, filled with plot twists galore and populated by characters who are utterly real and undeniably appealing. This novel is written in the voice of a natural-born storyteller.” — Jeffery Deaver, international bestselling author of The Bone Collector

"An audacious, inventive mystery, a thriller of ideas, and—here's irony for you—a novel about sleep to keep you up late. Anna O reads like a dream but unsettles like a nightmare; the premise is original, the writing stylish, and the payoff unforgettable. You won't forget her name."  — A.J. Finn, #1 New York Times bestselling author of The Woman in the Window

“Anna O takes a spellbinding look at a sleeping disorder that sounds like the stuff of horror movies…With masterful control over a large cast of characters plus a plot that keeps you guessing, Blake proves to be at the top of his game with this story. Reminiscent of The Silent Patient in the best ways.”  — Stephanie Wrobel, bestselling author of Darling Rose Gold
