I have to admit that I spent most of the time waiting for Raffe to return. 
 I was a bit upset to be back to the whole "find Paige and recover wings" thing... but it turned out to be really interesting. We learn more about Raffe's past through a very interesting new "character" named Pooky Bear. Seriously guys, this was the best part of the book. Everyone trembles at the sight of Pooky Bear! 
 We also get to know more about the scorpion like creatures from last book and the truly horrible, the dark experiments that are being conducted and their place in angel politics. I cringe just remembering about them. This series is much darker than I thought it would be. 
 Pieces start to fall into place. 
 One of my favorite scenes is little after Raffe and Penryn reunite, when they finally can talk to each other. (view spoiler)[ He cries! That's so cute! (hide spoiler)] 
 Let me dive into the third book and finish the series...
