I didn't especially like Katie. A lot of the story was spent explaining her unnecessary life story and dealing with her PTSD...none of which added anything to the story of the missing little girls. The antagonist had an off-the-wall, more than crazy motive for his murderous crimes with the little girls. We read mostly from his point of view, and there were very few clues to help us guess who this nut might be. Actually, there were lots of possible suspects, the story moved along so quickly there wasn't really time to digest it all. I suppose that it's an okay beginning of a new series, but what it lacks is creditability. Katie’s background needs lots of work if we are expected to believe that she became a detective almost overnight much less a skilled crime investigator. Most of the side characters were okay although I had my doubts about Dr. Dean who fawned over Katie like she was royalty. ( )

Unrealistic ending, saved by ground collapse. ( )
