21: Flight of the Code Monkey by Kid Wigger A creative set of ideas. This is the story I follow and wait impatiently for each chapter. You get vested in the characters and the author builds a pretty complete "world."
At times their are sections which go a bit too long on details that slow the story down more than I like. But I am not one to talk to much about that, knowing how an author really wants you to see what is in their mind.
