Warning - this is not quiet a HEA. AAAAAAAAAAAAck! And I still loved it, up until about the last chapter, and I'm willing to overlook that since I can go read the next book immediately. 
 Loved: 
 Cat and Bones - both great, strong characters who were enjoyable to spend time with 
 How Cat grew throughout the story 
 Disliked: 
 There was a tiny ick-factor for me when Bones moved from mentor to more-than-mentor. 
 That last chapter, which felt a bit out of character and much more like a set up for the next book. Which I'm going to go and read now.
