Torment (Fallen #2)

Fallen angel Daniel and his mortal love Lucinda think they are safe but evil forces are massing against them. As Luce learns more about her past, and discovers that the lives she's already lived hold the key to her future happiness, she starts to wonder if Daniel has told her the whole truth. What if his version of events isn't the way things happened? What if that means that she's really meant to be with someone else?
