Mysteries of Cove

"Trenton, Kallista, and their friends from Discovery trace the origins of the dragons to San Francisco where they must battle a powerful white dragon in order to save the city and everyone who lives there"-- Provided by publisher.

Far beneath the city of San Francisco is the key that could help Trenton and Kallista stop the white dragon's power from spreading across the world. If they don't act fast, the entire human race could be enslaved to the white dragon, and Kallista's father, who they've finally found, could be under the strange spell that has him contently doing the dragon's bidding forever.

Trenton and Kallista travel to a steampunk version of Seattle hoping to find Kallista's missing father, but instead find themselves in the middle of a war between the Order of the Beast, who worships dragons, and the Whipjacks, who are building weapons to destroy the animals.
