The Dragon Whistler (Secrets of the Soul Treasures)

Willow McLain thinks dragons exist only in fairy tales...until she accidentally wakes one from a thousand-year hibernation. Who knew sneaking away from summer camp with her cousin Ben to explore an old abandoned hotel could land them, and their entire town, in danger of becoming dragon flambé? Who could have guessed that the slender whistle carved from bone Willow found in the hotel attic was stolen from a secret order of Dragon Guardians who'd spent the last thousand years watching over seven hibernating dragons? Now, as one of the dragon's "Whistlers," Willow is the only one who can play the magical tunes that control her. Too bad things don't return to normal once Willow lures the dragon back into her den. And when one of the Guardians turns evil, planning to use all seven dragons to control the legendary Dragon Treasure, Willow must wake her dragon again to help protect mankind's only source of hope.
