I thought this book was okay, but not great. It has a really interesting hook and the main characters are well developed and likable (except for the antagonist, of course, who is appropriately unlikable and, unfortunately, a bit one-dimensional). The relationship of the hero and heroine develops over time, which I always appreciate in a romance. I'm not a big fan of the "love at first sight" concept and so I liked the way their feelings developed as they got to really know each other. 
 However, it gets a bit tedious and repetitive in parts and I found myself wishing that the author would quit describing the characters anticipation of what was coming, and just get on with the action already. A bit too much of the characters' angsty guilt/blame over things that couldn't be fixed at times. Not that those emotions aren't normal, I just don't feel they needed to be described over and over and over again. And worse, in my opinion, is when the author would finally get to a key scene that she has been building anticipation for over several pages, and suddenly the narrative skips over the "big revelation" and goes straight to the aftermath. She didn't do this every time, but often enough that I found it annoying. 
 The ending was mostly satisfying, except for one key scene that I was hoping for that wasn't included. The story just ends before a main character gets some good news (trying to write this without spoilers), and I had really been looking forward to reading the reaction. I feel a bit cheated at not being given that scene. 
 As I said above, the main characters are well written and likable, especially Low Down/Louise. I would say, however, that by the end of the book she starts to feel a bit too saintly and capable. She can do anything! It starts to be a bit eye-roll inducing. 
 Overall, a satisfying read for fans of romance.
