About This Book
Nobody expects a bunch of funny little cousins to take on dragons, rat creatures, and ancient secrets—but that's exactly what happens here! Fone Bone, Phoney Bone, and Smiley Bone dive headfirst into danger, facing Kingdok and the Red Dragon in battles that could decide the fate of the valley. When the Hooded One rallies his army, the real fight for the valley's future begins—and it’s bigger than anyone imagined.
