Charlie is in quite a predicament. After sending Reyes to a hell dimension, he doesn't come back the same, and he brings some really bad things with him. There is a lot going on in this book. Charlie is trying to bring Reyes back to herself, a murderous priest, and avenging angels. Definitely one of the more exciting parts of the series. Beware the ending if you don't have the next book already. It's a doozy.
