Best-selling author Rick Riordan presents a standalone quest adventure based on Filipino mythology by Roshani Chokshi, author of the best-selling Aru Shah series.
Corazon yearns to finally start training as a babaylan (a mystical healer and spirit guide) under her powerful guardian, Tina. When her magic awakens, Corazon plans to bring her parents back to life.
Tina sends Corazon on a quest to fashion a key that will restore balance between the human and spirit realms. But Corazon must move quickly, before a vengeful ghost gets through the Spirit Mirror and all hope is lost.
Roshani Chokshi pays tribute to her Filipino heritage in this book that has all the magic, sparkle, and heart that made her Aru Shah series a fantasy classic.
