Dragon Realm

When twelve-year-old Billy Chan finds out his parents are sending him to a summer camp in middle-of-nowhere China, he doesn't know what to expect. There he meets fellow campers Dylan, Charlotte, and Ling-Fei, and together they stumble upon an age-old secret: there are four powerful warrior dragons hidden deep within the mountain behind the camp! They need the children's help to set them free before evil in the guise of the Dragon of Death is unleashed upon the earth. Billy and his friends must set off on a dangerous adventure that will take them to the heart of the Dragon Realm.

Billy Chan was having the summer most twelve-year-olds dream about—bonding with his very own dragon. But Billy's friend Dylan has been kidnapped by the Dragon of Death, and the only way to save him is to travel through time with his friends and their dragons. Will Billy, Charlotte, Ling-Fei, and the dragons get to Dylan in time? And can they work together to stop the Dragon of Death from destroying the past?

Billy Chan and his friends have been transported 5,000 years into the future where the evil Dragon of Death has become ruler of Dragon City. Humans now live to serve the dragon population, and it's no different for Billy, Charlotte, Dylan, and Ling-Fei. After losing contact with their own dragons, they're determined to track them down in this new city, even if it means putting their own lives at risk. But one dragon has turned to the dark side and has no plans to return.
