I sort of have conflicting feelings on this book. I think I went into this book expecting a urban fantsay with a dash of mystery thriller. What I got was mystery thriller with some science ficiton elements. So my expections did not meet the book. I really loved the main character in this read and the twists and turns of the story. I also liked how this story was mostly set in the new york public libary. I howevr found the numerous narrarors voices had to idenify who was was. It also alot of story telling and that i struggled with. It was quick read, but at the end minus the main character it was hard to care about anyone!!
