Description

From Pura Belpré Award–winning author Guadalupe García McCall comes the first in the Seasons of Sisterhood trilogy: a reimagining of Sophocles’ Antigone set in the world of her bestselling Summer of the Mariposas.

As fifteen-year-old twins Delia and Velia plan the launch of their Magic-Twin Tour with their father’s Tejano band, a sudden supernatural attack on their father derails the family. Papá is delirious with a susto, a fright so awful that it allows a mysterious supernatural being to begin slowly sucking the life out of him.

As the twins hunt down his attacker, a wider world of borderland monsters opens up to them. Soon the girls must choose: Should they follow a divine mandate to become monster hunters for the goddess of death? Each twin has her own decision to make, with her own guide from the Aztec pantheon–Quetzalcoatl guiding Velia, and Xolotl advising Delia.

Can the sisters obey the will of the gods while saving their father’s life? Anything can happen within the magical realm of the borderlands.
