Had a lot of elements from other books and tv shows so was entertaining. I saw the first twist coming from awhile away. The second twist not so much. However, I agree with many other reviewers that the ending was disappointing. It was unsatisfying and had me going "seriously?!" I personally don't like it when the evil people get away with stuff and it seems like a lot of others don't either. Also, for someone supposedly so intelligent, put together and a psychiatrist to boot, Dr Hale is impulsive, has no common sense and doesn't think ahead. It's just not believable for a character to be so contradictory.
