I had read the sample of this book on my kindle but didn't read it until another author (Raye Wagner) recommended it. 
 Oh. My. Gosh. 
 I knew from the sample it was good, but once I read the whole book I was CAPTIVATED. 
 Penryn is so strong, a quick thinker, and the dynamic of her relationship with her family correlates perfectly with the main plot. 
 Penryn is the responsible caretaker of her 7 year old wheelchair bound sister and her mother, whom suffers from... Pure crazy. Which, is hard enough on a teen as is, but add to it that the world is post apocalypse, Angel's are roaming-and destroying- the earth, and what the Angel's haven't destroyed, the neighborhood gangs claim what's left, Penryn has resolve of steel to do whatever it takes to keep her family fed and safe. 
 She knows they can't stay in one place for long, that they need to move before a Gang comes to claim their temporary home. But while trying to escape one evil, they run into another: Angels. Except, something is wrong. The Angels are fighting each other, with the unbalanced odds of four to one. Not a big deal, let them kill each other. But Penryn has just exposed her family by trying to move shelters, and when one of the Angels comes after them, Penryn dives in, knowing the only chance of their survival is to help the one Angel that could almost hold his own against the four others. 
 The attacking Angels retreat, but not before hacking off the lone Angels wings, and worse yet, kidnapping Penryn's helpless sister as punishment. 
 Now, the only hope Penryn has is the Angel that's slowly bleeding to death as his snowy white wings lay bloodied and crumpled on the ground. 
 He could be her only chance at saving her sister, but what will it cost her? 
 The author knows how to slow things down to precise moments, explaining it in fantastic detail, and how to speed thing up so it is fast paced. And the action! Honestly, the action in this book is some of the best written action scenes I have ever read. 
 If you love YA fantasy books, this one is worth the read and I'm willing to bet will be on your favorites shelf soon enough. 
 So, seriously. Read it. Now. You really, really should.
