There are so many unanswered questions?? Like what happend to Lucifer, to Sam? Is the barrier really gone? What happened to Claude, Khali? To Nash and Nika? Reza? To the Guild? I enjoyed this series but I have to say, 6 books would have been enough. Also, they should have found their way to each other a lot sooner. It was enjoyable, but if you are expecting answers to every question you are not going to get it.
