Tu Books Summer of the Mariposas

In the attic of every family, there's a box of old photographs. Next to the smiling school portraits and awkward holiday gatherings, there's always one that makes you pause. It's a picture of your mother or grandmother as a young girl, standing with her sisters. Their expressions are a mix of defiance and mischief, their arms slung around each other in a way that’s both a hug and a dare. You don't know the full story behind that photograph—the secret adventure they had that summer, the promises they made, or the dangers they faced together. You only see the result: an unbreakable bond forged in a moment you can't access, a shared history that hums just beneath the surface of every family gathering.

That sense of a hidden, epic past, of a story that belongs to the women in a family, is what drove Guadalupe García McCall to write Summer of the Mariposas. Growing up on the border between Mexico and the United States, McCall was steeped in the rich folklore and myths of her heritage, from the terrifying tale of La Llorona to the magic of local healers. She noticed how these epic, ancient stories often felt distant, like artifacts in a museum. She wanted to bring them to life, to hand them to a new generation of girls who looked and sounded like her and her sisters. As an author and educator, she crafted a journey that blends the classic structure of a hero's quest with the vibrant, lived-in reality of five sisters on an unforgettable, supernatural road trip.

Module 1: The Call to a Mythic Adventure

The story begins with a supernatural event. A swarm of butterflies ends a long drought, a symbol that change is coming. The five Garza sisters—Odilia, Juanita, Velia, Delia, and Pita—live in a state of chaotic freedom. Their father abandoned the family a year ago. Their mother works long hours, leaving them unsupervised. This absence of authority is a double-edged sword. It breeds incredible self-reliance and creativity, but also neglect and a simmering rebellion.

It's in this environment that their adventure begins. While swimming in the Rio Grande, they discover a dead body. This is the catalyst. Your greatest challenges often appear disguised as problems to be reported to others. The sisters’ first instinct is to call the authorities. But adolescent logic, mixed with a deep-seated distrust of institutions like the border patrol, takes over. They fear their mother's wrath. They worry about their summer freedom being revoked. The twins, Velia and Delia, are even concerned about how they'll look on the news.

This is where Juanita, the fiery second-oldest, steps in. She discovers the man is from a town in Mexico called El Sacrificio, near where their own estranged grandmother lives. She sees this as a quest, a mission. So, the second insight emerges: a compelling mission can reframe a crisis into a purpose-driven journey. Juanita convinces her sisters that returning the body is their destiny. It's an honorable act that will make them heroines. More importantly, it gives them a reason to go to Mexico, a chance to find their grandmother, and maybe, just maybe, find some answers about their absent father.

This leads to a power struggle. Odilia, the eldest, is the voice of caution. She sees the risks: the unreliable car, the dangers of the border, the illegality of it all. But the younger sisters, fueled by a sense of adventure and moral righteousness, outvote her. In the absence of established authority, leadership is seized, not granted. Odilia tries to be the responsible one, but her sisters’ collective will is too strong. They steal the car keys and essentially force her to come along. Her reluctant participation marks the official start of their odyssey. She may be in the driver's seat, but she’s not entirely in control.
