Okay, so I'm not going to lie; the only reason I read this book was because I felt almost required to in some sick way considering I had read the first books. I guess in a way I wanted closure... and I also have a problem with myself if I don't finish a book or a series of books after reading even one of them. But that's neither here nor there. 
 I actually enjoyed this book. Luce wasn't horribly obsessed and all consumed with her love for Daniel like it had been in the other books so I felt like I was actually able to focus on the literary aspects of the book. The plot was pretty interesting (although it was sometimes hard to follow and found myself re-reading certain parts because I got confused). Luce's realization of who/what she really is was interesting and even though I felt like they could have brought it more throughout the other books, it was interesting and relieving to finally have all the questions answered (instead of continuing to pile up with no actual responses like in the previous books). 
 Lauren Kate did a good job describing "the fall" and the way in which everything took place in heaven. Lucifer became an interesting character and in some ways it was hard not to feel sorry for him after seeing the way in which things progressed between Luce and himself. 
 This is kind of random, but I felt like this was the first out of all the books in this series that Lauren Kate suddenly through in tons of 10 point vocabulary words. I actually had to look half a dozen of them up when reading this in my Kindle because I wasn't really 100% sure what they meant... Did Kate suddenly get a hold of a Thesaurus? I mean, good for her for using those words because they were pretty meaningful and rich in their meaning, but I don't remember her using such profound or advanced vocab in the other books... Weird. 
 All in all, this book was much better prepared than the earlier ones in the series and thankfully Luce grew a pair so that we could actually recognize the other literary assets of this book. There were still parts that lacked depth and there were still parts that irritated me to no ends and so I give 4 stars out of 5.
