This is the second book in Lauren Kate's Fallen series. This book takes up immediately after the last book ends, with Luce and Daniel fleeing from Sword & Cross reform school. Daniel has teemed up with Cam to take on this new threat to Luce, and has let Luce in on close to nothing of his plans. He also takes her to a new school, one where the children of angels and humans, called Nephilim, also attend. 
 Luce is there without Daniel, however, and that seems to sting a bit. In this book, Luce and Daniel have some problems, which was weird compared to last book. And in truth, I wasn't a fan of the way that there were times, when they have this multiple-lives spanning love, that they use the term "break up" a few times. I'm not sure that that would/could happen. But it seems that it might. 
 Luce also begins to learn about her past lives in this book through the shadows that we saw in the last book. This was a totally intriguing idea to me, and a totally cool one as well. Able to see past lives just by calling a shadow to you? 
 In the end, we're left on a cliff hanger, with Daniel and Luce still somewhat fighting, Luce having found out several choice things that Daniel and Cam, as well as the other angels, seem to have neglected to tell her. 
 All in all, this book was a good continuation to the series, and we see a lot more development of Luce, but we see very little of Daniel at all. The next book promises to be very interesting, and I can't wait to get my hands on it.
