Sabertooth Mountain — John Vornholt

High in the Forbidden Mountains of Dinotopia, sabertooth tigers prowl and hunt, far from humans and dinosaurs alike.  In this chilling, Kipling-esque adventure, a daring 12-year-old boy is forced to join a sabertooth clan.  Then disaster strikes, and he must brave the treacherous crags of Sabertooth Mountain--for the good of all Dinotopians!
