This was a good, quick read. But I think that the heroine caved a little too quickly. One minute she hates cops, then BOOM, she loves them. Seems that a life time of dislike for cops was a little to easy to get past.
Other than that, though, I did enjoy the book and thought it was well written. For a short novella it was pretty well fleshed out. I don't expect to get to know the characters all that well in such a short time or have a ton of back-story. It seemed like there was enough in this, though, to make it fun.
