Dinotopia: The Sunstone Odyssey

After a rogue Tyrannosaurus kills their father during an expedition in Dinotopia's outer jungles, twin brothers Drake and Jacob Gemini are set on opposite paths. Jacob falls in with the Outsiders — a faction of humans with deep contempt for dinosaurs — while Drake chooses to become a guardian of Dinotopia, defending the bond between its human and dinosaur inhabitants. The Sunstone Odyssey follows Drake's journey across the island continent as the brothers' conflicting loyalties push them toward an inevitable clash.
