I have a serious case of love for this series even if it's barely two books in. I was so happy to see how the relationship between Knox and Harper is evolving, and even more so the fact that although they're demons, they have real arguments, it's not all roses and unicorn poop. 
 The plot is fantastic. It's hard to review it without revealing too much. This book was perfectly tied into the first one when it comes to the characters yet it's still a fresh storyline. It has a great amount of humor, some seriously cringe worthy parts and I had a holy crap moment there too. I don't know if it was just me but I swear Knox seemed a little softer in this one, sweeter even, although only when it comes to Harper. Maybe because he's such a scary demon, when he calls her "baby" it just sounds even better. I wish I could say I kind of saw the whole wing thing coming but not to that extreme - that was the holy crap moment by the way. It was amazing !!! 
 I can't wait for the rest of this series, as well as all the other Ms. Wright is working on. They're just such solid books/stories that it's always a shame when I reach the end.
