It’s finally here! Anna O, the gripping and compulsive thriller by Matthew Blake, publishes today in the UK with HarperCollins / HarperFiction.

Anna O tells the story of Anna Ogilvy, a young writer suffering from ‘resignation syndrome’ – a rare functional psychosomatic disorder that leads to the murder of two people – all done while Anna is asleep. 

Since its North American publication, the debut thriller has woken up the nation with its incredible chart success. It was an instant Canadian bestseller, reaching No.1 on the Globe and Mail charts. The thriller was selected as an Indie Next Pick for January 2024 and was chosen as an Amazon BOTM and the January Sarah Selects Book Club pick by Amazon.


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.

Congratulations on publication, Matthew! If you haven’t already, you can get your copy here.
