4.5 STARS 
 I honestly don't know what to say. I've been looking for an action/thriller series for a while now and this is it. This is the series. I still have to read the novellas (Betrayed, Forged and Played, I believe) but... wow. That was one hell of a ride. 
 This book was about Nick. As much as I want a whole frigging 300 book series on Cas (he's so cute, isn't he? 8'D), I do have to admit that this book was so freaking amazing with his point of view. It was amazingly structured and I loved the relationship between Nick and Lissy. 
 The plot was, as always, action-packed and rimming to the top with mystery until BOOM answers and BOOM plot twists. Amazing series, amazing writing; can't wait for Jennifer Rush's new fantasy series!
