From the author of The Graham Cracker Plot, a story about two friends playing finders keepers for the missing loot of Al Capone.

Christa spends every summer at the most awesome place in the whole world: her family's cabin on Whitefish Lake in Wisconsin. Only her dad recently lost his job and her parents have decided to sell the cabin. But not if Christa can help it. Everyone knows there is Al Capone blood money hidden somewhere in Whitefish Lake, and her friend Alex's cranky grandpa might have the key to finding it. Grumpa says the loot is gone, or worse-cursed!-but Christa knows better. If she finds it, she can keep it and save her family and their beloved cabin.
