Most of the time my complaint with books is that they end too abruptly, but this one actually started too abruptly for me. I didn't have time to get to know or care for the characters before they were thrust together, and it took me a little while to get into it. I did end up liking it, although the middle was my favorite. As I said the beginning was a bit too fast, and the ending a bit too slow where I started losing interest and all the crazy sex was getting to be "yeah, OK whatever." But that middle part was super hot and I liked their connection and interesting dynamic.
