Joe Stoshack lives for baseball. He knows everything there is to know about the game -- except how to play well. His specialty is striking out. Stosh feels like a real loser, and when he takes a low-paying job cleaning a bunch of junk out of his neighbor's attic, he feels even worse -- until he comes across a little piece of cardboard that takes his breath away. His heart is racing. His brain is racing. He can hardly believe his eyes. Stosh has stumbled upon a T-206 Honus Wagner -- the most valuable baseball card in the world! And he's about to find out that it's worth a lot more than money....
