Query: A Thriller Worth Reading

This was my first book by Michael Prescott and I must say it was very good. You didn't know till the end how poor Kaylie McMillan was going to get away from this evil man, Dr. Cray. The whole concept of being hunted was intriguing. The characters and the story was very believable, full of lots of suspense and excitement. There were times the book dragged a bit but it wasn't too bad. I'm definitely looking forward to reading another one of his books.
