Twelve-year-old Autumn is a beastkeeper at Inglenook School for Magicians, which she secretly dreams of attending as a student. Instead, she must care for Inglenook's menagerie of dangerous creatures so the king's future monster hunters can study them.

Everyone else thinks that he was devoured by the terrifying Hollow Dragon, but Autumn isn't so sure.

Together they uncover the dark truth that lies at the heart of Inglenook School - because every school has its secrets...
