Query: A Fast Action-Packed Read

I picked up this book on a whim, and I'm glad I did. This is a fast, engrossing read. The mystery was fairly easy to figure out early on, but it was interesting to see the characters process the clues and find the answers. A very strong female main character didn't overwhelm the story but pulled it all together. A fair amount of violence is involved, so if that bothers you, you might want to skip this one.
