Chelsea at Lichfield


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.
