A simmering tale of magic, adventure, and the extraordinary bond between a brother and sister who'd journey to the ends of the Earth to save each other. From the acclaimed author of Loteria comes a heartfelt story rooted in Mexican magical realism.

Ten-year-old Lola has always been touched by magic. In her Mexico City home, built around a towering tree, she is accustomed to enchanted blooms that change with the seasons, a sandbox that spits out mysterious treasures, and mischievous chaneques that scuttle about unseen by all but her. Magic has always been a part of her life, but now she must embrace the extraordinary as never before.

Ever since The Thing That Happened, Lola's brother Alex has been sick. As his condition worsens, something begins eating away at the tree, causing its leaves and blossoms to crumble like ash. The two are related, Lola is sure of it, but how? Seeking a cure, she visits a grocery store oracle who bids her to follow the chaneques down one of their secret passages... into a hidden world.

Here in Floresta, a land of myths and monsters and marvels untold, lies the key to healing her brother. But the kingdom's young queen stands in the way. Lola must use her wits and face her deepest fears if there's any hope of saving Alex in time.
