Loved this one so much, starting with the cover. (OMG, that cover is the sexiest thing, ever.) 
 At the end of the previous book, Jonathan comes to realize that he assumed way too much about Brandon and failed him miserably. Bran was an absolute wreck when he went back to Jonathan and let him have it. So they both had reasons for wanting to move forward (more than just the money or pride). And with their new understandings, things start much better than they did the first time around. 
 Neither is perfect, so it pleased me to no end to see them still making mistakes in this story. Bran has to answer some tough questions to Jonathan, and Jonathan has to answer a few of his own as well. Since the story is told from both points of view, we see inside both of them as they make their discoveries and progress. And wow, is it a subtle transition and so well done. By the time their contract is over, their ending makes complete sense. 
 This story is not for the faint of heart as far as pain goes, but there's still no blood (Bran's hard limit). Bran does NOT like pain, but he does endure a lot of it, so the descriptions are quite vivid. 
 In the middle of the story, we see Devon and Nicky (from Master Class) for an evening. Quite an interesting evening for Bran, that one. I was sort of hoping toward the end of the story that Bran might think of talking to Nicky again since Nicky had gone through some of what Bran was going through. 
 If I had to find one thing felt slightly off to me, it was Bran's behavior on the plane. That felt a touch forced (as a story element) for some reason. Not to say that it couldn't have happened for the reasons it did, just . . . *shrug* It's nit-picky as far as issues go, and quite possibly just me. 
 So, I loved it. If you can handle the hardcore BDSM, this series is definitely for you. 
 And because she said it much better than I, I'm linking to Emma C's review also.
