Green City Wars by Tchaikovsky

 Green City Wars is the story of Scotch, a genetically engineered racoon who has left the corporation that made him so he can go freelance as an investigator,. The story has a noir feel, but Scotch is more Jim Rockford than Sam Spade. The twists, turns, shifting alliances and double crosses are on par with _The Sting_. Along the way, we meet a saint, a technology adept turtle, a vengeful possum, and a pigeon who craves stories, Green City Wars doesn't take itself too seriously; it is a lot of fun to read. I loved this book and would read a sequel if Tchaikovsky wrote one.
