Falling Away by Penelope Douglas is the third book in her Fall Away series. It can be read as a stand alone but If you plan to read the other books and don't like spoilers I recommend your head the series in order. 
 This book had so much angst and emotion and buried passion I was just blown away. I have NOT read the previous books but did get a full and complete break down of Bully by a close friend that was equally blown away by that story. Plus I can handle spoilers if the book/series/author is this awesome. 
 KC and Jax have a very strained history. They never really hung out, they barely interacted in high school but they ere both so intrinsically aware of each other that when KC comes back to town for the summer the latent passion between them cannot be controlled. 
 KC has a very private and miserable past. Her home life was very difficult one loveless and she is still wearing that pain by continuing to go by KC and not her given name of Juliet. 
 Jax's past was beyond messed up, and while the author doesn't go into great dramatic detail of all that happened to him as a young boy and early teen, you understand and feel for him. 
 The story has a dual-POV which allows you into the sometimes ridiculously caveman-like thoughts of Jax that I really enjoyed. 
 I saw the plot twists/dramatic moment coming but it was still so well written and every page was a treasure, that regardless of the inevitable confrontation you weren't ready for it to end.
