But the new world has not been without its perils as Billy and his friends have just barely escaped the clutches of the Dragon of Death and learned of a betrayal from someone they trusted. That betrayal leads to Billy's friend Dylan being kidnapped and taken through a time portal. Now Billy, Charlotte, and Ling-Fei must travel through time on their dragons to save Dylan. Will Billy and his friends get to Dylan in time? And can they work together to stop the Dragon of death once and for all?"-- Provided by publisher.
