** spoiler alert ** 
 This was an explosive conclusion to this trilogy and I found it be the best book of the three. 
 ________Spoilers Below___________ 
 I am altering my rating after coming down from the 'just finished the book high' from five stars to four. Because upon actually thinking this story over there are some things that seemed to have been left unanswered or unexplored. Why wasn't there more with Michael? Who or what were the Hellions before? I was totally predicting some time-warping twist that showed that the Hellions used to be humans or something but that just sort of petered out. Was there ever any serious discussion about how short Penryn's life span is compared to Raffe's? I thought there would be some sort of revelation about a the nephilim bloodlines? Where is frick is God? Was Uriel right? Was Gabriel just making things up? Nobody seemed to worried about that? I don't recall if it was ever mentioned but there is traditionally seven archangels, not just four? Where are the rest? Are the sixers2.0 (now included with heads of the consumed) just chilling with the sharks or did they go elsewhere? I just have questions, and some of them might just be because I should have re-read the first two books or something but I don't think all of them are answered that easily? Sorry for the word vomit/rant.
