Okay this book had me seriously stressed. I'm not giving away any spoilers but this has literally drained me emotionally. The story was great but there was so much raw emotion and intensity that I felt like the action was happening in front of me. 
 There many challenges for Cat and Bones in this book, more than usual in fact. The author had me gasping a few times in some WTF moments. Howver, the story was engaging and I just couldn't get enough. Bummer I have to wait till next month for book #5.
