Lost City

Andrew, the son of a Dinotopian innkeeper, makes a strange discovery one night when a hooded dinosaur leads him and two friends to a remote, sealed-off city. When they begin to explore the forbidden area, the trio are thrust into a dangerous adventure–one they can survive only if they can put aside their chronic rivalries and come to understand the lost race of TroÜdons, who have existed there in seclusion for centuries.
