I really do love this series but I didn't feel like we were given any more information about Charlie and Reyes in this book. It was a little frustrating to have the mysteries of the Grim Reaper and the son of satan be dragged out. I hope DJ doesn't drag the plot just to write more books, like so many authors do. On a positive note, the dialogue and characters are a crack up as usual and was a fun and exciting read overall.
