Having been defeated in Australia and Antarctica, Mr. Bones hides out somewhere he's sure he won't be found: the Moon! But the joke's on him, as Mike and Shannon take to the space to face off against their arch-nemesis in a lunar showdown of dino-sized proportions! But when they finally track him down, they realize Mr. Bones isn't at all what he seems to be . . . Each book in this action-packed series is written and illustrated by the Eisner-Award winning creator of Tiny Titans: Franco!
