Swindle by Gordan Korman

Swindle is an amazing book about a kid who finds a rare Babe Ruth rookie card but a collector rips him off for it. He comes up with the ultimate plan to get it back. He gathers up a whole bunch of people, who each have some certain skill, to break into the guys house and get the card back. If I had to make a list of my favorite books this would definitely be the second one on the list.
