Loved this book! Curran and Kate are lured with promises of panacea which helps babies and teens from going loup. All sorts of things happen, including a very stupid mood on Curran's part that had me literally crying for Kate. Someone very memorable dies too which was an extremely sad scene to read (another cry). I think a book is very good if it has you so invested in it you have emotional reactions. This is a great series/book.
