This happens to me a lot more often then I would like. I try to keep my expectations low so that I won't be extremely disappointed. But even in those categories there are definitely books which I didn't expect much out of but ended up loving.
At first I was kind of excited about Criminal but by the time I got around to reading it, the excitement had faded away and in it's place was a heavy dose of skepticism. I ended up loving it though. And honestly I probably shouldn't have loved it as much as I did but the book was fantastically written. Terra definitely knew what she was doing.
