Firsly, I was extremely lucky to get this book in a Goodreads giveaway! Especially at this time when I'm too broke to afford new books, so thank you Susan Ee!Wow. I haven't felt this excited over a book in a while. I read this book in one sitting because it was that great. This is what I want from YA Dystopia. It's funny, it's riveting and it has sexy romance. It's just brilliant. I'm sorry for gushing.So I was skeptic over reading this because angels and YA haven't really mixed well at all. But this is how you do it and it's by a self-published author!I love Penryn. She is such a strong, badass, non-whiny protagonist. Her love for her family is real. She is a real character. Her thoughts were never one-sided and "pure". She wasn't portrayed as perfect with an immaculate sense of what is wrong and an undying loyalty to everyone. She had her doubts. She did not stray and get sidetracked by the "greater good" and suddenly lead on a rebellion. She is a teenage girl after all!Her relationship with Raffie is my favourite of this genre so far. They had funny, honest conversations and the sexual tension between them wasn't thrown at you, it was so subtle but so effective.The plot itself is very interesting and I hope it is better developed in the sequel. I thought it was a little shaky and relying too much on the common knowledge of the events that occur in this book. I want to know more about how or why the apocalypse happened and more about the angels and the remaining humans. The pacing is good enough, though some parts did feel too dragged on, only because I wanted to know more and I was so caught up in that world. It's very gripping, particularly toward the end. I usually have a hard time connecting with action scenes but Susan Ee wrote them in a way that helped me stay in the story. It's a dark, twisted story with a kickass heroine and I recommend it to everyone and anyone. Especially fans of Supernatural!
