Anna O is an usual, twisty page-turner unlike anything you’ve read before, think The Silent Patient meets Sleeping Beauty. It follows the story of Anna O who stabbed her two friends, fell immediately into a deep sleep and hasn’t opened her eyes since. Is she guilty, was she sleepwalking, just what exactly is possible when you are sleeping?

The story is told through a mix of POVs and timelines which include snippets from Anna’s diary which build up a tense and sinister story that reveals itself layer by layer to a whiplash inducing conclusion.

The concept of this one had me absolutely hooked and certain experiments and thoughts within the book really got me thinking. I honestly would have loved a little bit more of those science bits rather than the friendship back story, which felt a bit drawn out and almost filler like, but maybe that’s just the psych nurse in me!

The book is being billed as an upcoming global phenomenon and I can see why, while it may not be the most spectacular literary thriller it is a fun read which people will not be able to put down and will want to discuss immediately once finished.

A must read for anyone looking for a gripping, mind-bending psychological suspense with a touch of whodunnit, this one is definitely for you.
