FRNK: Prisoners (FRNK #7)

Outside a wooden fortress built around the wreckage of a commercial jetliner, Frank, Frank, and Kenza wait in the snow, wondering how to save their friends imprisoned in the cargo hold. The mystery of how an airplane came to crash-land in prehistoric times is intimately intertwined with the mystery of Kenza's past. Will Frank (the kid) and Kenza succeed in rescuing Justine, Gerard, and the gang? Will Frank (the short guy) bring the wrath of the cannibals down upon them? What does all this have to do with an army of snowmen and a flock of quasi-domesticated dinosaurs? Find out in FRNK vol. 7!
