12-year-old Autumn is a beastkeeper at Inglenook School for Magicians. She tends to Inglenook’s menagerie of monsters so that the school’s young magicians—the king’s future monster-hunters—can study them. When she isn’t working, Autumn searches for clues about her twin brother’s mysterious disappearance. Everyone else thinks that he was devoured by the feared Hollow Dragon, but Autumn is convinced that she’s heard—and glimpsed—her brother calling to her from the castle. But who will believe the suspicions of a lowly beastkeeper? So when Cai Morrigan, the famous 12-year-old magician prophesied to one day destroy the Hollow Dragon, comes to her for help, Autumn agrees on one condition: that the “Chosen One” helps her find her brother, and uncover the dark truth that lies at the heart of enchanting Inglenook School once and for all.
