It definitely leaves you wanting to know more, so don't read it without being prepared to get through a few of the books. In fact there are cliffhangers throughout the book that stop you from putting it down. The idea of children being used as experimental subjects is something I have come across before, and I think I can see some of the dilemnas that will arise in the future books. The pace of this book is just what you want from a thriller/suspense novel. Plenty happening to keep you interested. I think this book has a broad appeal, girls and guys both will enjoy it, and I'm glad the book challenge inspired me to pick it up.(less)
