“This story inspired by Sophocles’ Antigone seamlessly blends coming-of-age themes with folklore. McCall respectfully integrates well-researched Nahuatl vocabulary and Aztec mythology as she explores sisterhood, cultural identity, and blended family dynamics…. A rich, mythic story about selfhood and soul-deep family ties.”

—Kirkus Reviews, Starred Review

“Mesmerizing…. Via the girls’ propulsive, distinctly rendered alternating POVs, McCall presents an Aztec-influenced world teeming with magical creatures and powerful deities.”

—Publishers Weekly, Starred Review

“Readers will relate to the twins’ struggle to balance the head-and-heart decisions they make to find justice for their father and save Eagle Pass from a haunting, cruel landowner who wants to come back from the dead. This ­Mexican American twist on Antigone draws on ­compelling multideity legends to flesh out the first of three coming-of-age novels…. A must-purchase.”

—School Library Journal, Starred Review

Fall of the Fireflies (Seasons of Sisterhood #1)

Written by Guadalupe García McCall
Published by Tu Books

As sixteen-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 to begin slowly sucking the life out of him.

As the twins hunt down their father’s 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.

Look for the Spanish version, El Otoño de las Luciérnagas (Las Estaciones de la Sororidad #1).
