I enjoyed this book tremendously. The first page had me hooked and I read through the rest of the book with eagerness, wanting to know the outcomes. The main character loses her son in a car accident and sets out on a quest to determine what happened when she experiences some supernatural events. The events become more frequent and sinister leading her to a frightening conclusion. There were a few minor loose ends at the end of the book, which is why I only gave it a 4. I have read other books by Peter James and have become a fan of his.
