One of Rucka's Queen & Country novels - I read some of his comics about the same character (well, characters, but it is essentially Tara Chace's story) last year. The comics are good, the novel was better. It's a spy thriller, and exciting nasty stuff. He pushes the reader pretty hard in some of the more violent parts. However, if you are prepared to take a rough ride emotionally, the story definitely pays off. Great characters, great story.
