With a description below being all that was provided on Netgalley, I didn't really know what to expect from this book!

"THE WORLD WILL KNOW HER NAME
*The instant global phenomenon.
*Publishing in over 30 territories.
*The thriller that will wake up the nation.
This is the story of Anna O.
Coming 2024 . . ."

But the story turned out to be a fascinating read, with some decidedly meta aspects.

Sleep and dreams involve mysterious processes for most of us, even though these are processes that we undertake - quite literally - on a daily basis. Most of the time, we shrug off nightmares and are grateful to get a few hours of good sleep.

Anna Ogilvy - better known as Anna O - is not so lucky. A promising young writer, she inexplicably stabs two people one night, whilst apparently sleepwalking. And after that, she does not wake up at all.

Everyone is puzzled by the killings - not least because of the lack of apparent motive. Nor can Anna enlighten them, because she is not able to tell anyone anything, even if she were so inclined.

It seems that Anna has a rare disorder. But her situation does of course raise ethical questions. For example, about whether she can be held responsible for her actions - even while unconscious.

Enter Dr Benedict Prince, an expert in sleep-related homicides (who knew that that was a thing?) He is believed to be the last resort when it comes to solving the mystery of Anna's case. Mind you, Dr Prince has his own secrets to protect, so there's no telling how this situation will ultimately play out...

Outstanding..
The story of Anna O. Where does it start and where will it end? Hailed by the media as the crime of the century, an inexplicable and horrific double murder and a suspect who sleeps - and continues to sleep four years later. With a deft pen the author draws the reader in with beautifully crafted prose, an intriguing plot populated with a well defined and wholly credible cast and a compellingly immersive narrative. Lines between fact and fiction may well blur as the reader becomes completely invested in this tale of murder, mystery, science, justice and true crime. A one sit read, impossible to put down until that final awakening when the truth dawns.
