Query: A good read

This was a lot better than I expected - I think I got this one for free. The characters could have been a little better developed, but all in all, it was a story I could sink my teeth into and I didn't figure out "whodunit" immediately. Even though the story involves prostitutes, I don't know that I would exactly call it an "erotic thriller." But hey, if it sells books, whatever. Not fantastic, but definitely better than a lot I've read lately. It's worth a read, and I'll probably check out others by this author.
