Susie Sparrow's life has turned upside down. She's merged with Ferapont, who says he is an angel, and has dedicated her life to ridding the world of demon possessed people. Unfortunately she is also in High School. Trying to schedule fights around school, hanging out with friends and dinner with the parents might be too much for one girl with large flaming wings to handle. But don't tell her that.
This volume collects all three volumes of the hit novella series as well as the original short story that started it all. As an added bonus it also contains a never before seen end story, exclusive to this volume!
