Wow. Just, wow. I can't believe how much I loved this book. It had everything I look for in a book: an independent, kick-ass heroine, a sworn-worthy love interest, amazing world building, an interesting premise, intuiging dialogue, and a complex past for the main characters, and the male lead needs to be mentioned again, because he's awesome. I don't know how she did it, but Susan Ee has gathered up everything that I love and created this awesome book. 
 I really liked most of the characters. Penryn was actually pretty awesome. She took care of her disabled little sister and her borderline crazy mom and sacrificed everything she had to keep them alive. She is strong, kickass, and a really admirable main character, especially since she is only 17 years old. She seems like someone I would want to be friends with in real life; someone who protects the people she cares about the most, but can have fun too under the right circumstances (and if the angel apocalypse did come to earth I know who I'd be sticking by/hiding behind because I'm a coward). Penryn handles everything really well, and her drive to keep her family alive makes her really strong. 
 Penryn's mom was another story. I don't want to say that she was crazy but... she was crazy. Penryn does mention throughout the book that her mother was diagnosed with some kind of disorder, I'm not sure what, though I think could possibly be schizophrenia with the paranoia that she experiences. However, you can tell that she does love Penryn, if in an odd way. 
 And then there's Rafe. Oh boy I love this guy. Don't get me wrong, it's definitely not insta-love between him and Penryn, not even close. But when they get to know each other they definitely start to develop feelings. I really liked Rafe, and I loved the bond that developed between him and Penryn. 
 This book is somehow horrifying and intriguing, heartbreaking and comforting, disgusting and romantic. It is gruesome and disturbing at times but somehow that is what made it such a great book: the reality of it even though it is fiction. This is no Dora the explorer trying to find the rainbow mountain. It is a hardcore book with desperate characters facing life or death situations, and at the end you will have felt a whole array of feelings. 
 This book is gonna get you right in the feels, so prepare for this gruesome, lovable, inspiring, adventurous, romantic, and overall amazing story, because it is going to take you on one hell of a ride.
