I'm only rating this four stars, because this series had to end - I would've happily continued reading another gazillion books to get my Penryn/Raffe fix. Throughout the three books, the writing is exemplary - I'm in awe the writer made the mother and Paige central to the books, and weren't just there as filler...to give the MC a backstory and nothing else. That is so, so rare in YA books or any books actually, that I think this author is onto something special in her career :) 
 Also there was no love-triangles and yet the romance is thrilling, exciting, takes a near fatality to get going...but by jove! Even when they're separated, I'm counting down the minutes till they're together. The best books regarding Angel Dystopian I've ever read. If only I can find more books like this in my life!
