Forget the horror aspect of this book. Instead, focus on what an excellent thriller David wrote. Is it horrific? Yes, in parts. To me, though, this is a fast-paced, character-driven paranormal thriller. We follow Kate, Verne and Beans. We slide back and forth through time, building a picture of how Kate became to be the darkness haunting the Roanoke wing of an institution for the criminally insane, Moriarty. Verne is not all he seems either, with a clever twist where we discover who he is and his true motives. Running through this, we have Beans, a detective, who comes into his own in the latter part of the story. Beans is a nickname, not some weird parenting choice at his christening. How the story builds is a masterclass in suspense. What is real? What is hallucination? What is a time slip? Despite Kate’s horrific actions, the early part of the book details how she gets there, so at no point is she the villain, and the ending is satisfying, weaving in mythos and intrigue to come to the proper finale. On reading the author note at the end, it surprised me to discover this was a re-work of an earlier book. All I can say is David made the right decision to do that, because it culminated in a fantastic story.
