What to read after Just Like Jesse James?

 Four cousins, one lost treasure, one outcome. 

Attending a funeral, 18-year-old Lee and his three cousins learn that their late grandfather believed a treasure was buried on the family farm, hidden there by none other than Jesse James himself. Obsessed with the legend, he spent years digging for it but died before completing his search. Convinced that the old man was onto something, the cousins take up the treasure hunt themselves. But what starts off as a lark soon turns deadly when their shovels hit something solid.
