It’s the crime of the century.

Everyone knows the Anna O case. Everyone knows it was her fingerprints on the knife. But no-one knows the secrets of her sleepwalking. No-one knows whether she really meant to kill that night.

As a trial nears, the mystery reawakens. Is she innocent, or guilty?

It’s time to pick a side.

Anna O – the world will know her name.

Anna o hasn’t opened her eyes for four years. Not since the night she was found in a deep sleep by the bodies of her best friends, suspected of a chilling double murder.

For Doctor Benedict Prince, a forensic psychologist on London’s Harley Street, waking Anna O could be career-defining. As an expert in sleep, he knows all about the darkest chambers of the mind; the secrets that lie buried in the subconscious.

As he begins Anna O’s treatment – studying his patient’s dreams, combing her memories, visiting the site where the horrors played out – he pulls on the thread of a much deeper, darker mystery.

Awakening Anna O isn’t the end of the story, it’s just the beginning.

Joining the ranks of Gillian Flynn, A. J. Finn, and Alex Michaelides, Matthew Blake delivers the thriller of the year: a dark, twisty, and shocking mystery about a young woman who commits a double murder while sleepwalking, and then never opens her eyes again. THE WORLD WILL KNOW HER NAME What if your nightmares weren't really nightmares at all? We spend an average of 33 years of our lives asleep. But what really happens, and what are we capable of, when we sleep? 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 hasn't woken up since. Dubbed "Sleeping Beauty" by the tabloids, Anna's condition is 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 are the last hope of solving the infamous "Anna O'"case and waking Anna up so she can stand trial. But he 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 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 find out.
