Klondike: A Game of Ears
Publisher Description
When you receive a human ear in the mail, you have to play.
The game is called the Klondike. It's a criminal and dangerous affair, and Abe Schmidt wants nothing to do with it.
Unfortunately for him, he's caught up in the game, and if he's determined to survive, he needs to learn how to make puns, deal with wackily-named characters, and run from all sorts of troublemakers.
It's not a good book, but it's definitely a book.
