October 18, 2019. Cristina Rivera Garza travels from her home in Texas to Mexico City, in search of an old, unresolved criminal file. "My name is Cristina Rivera Garza," she writes in her request to the attorney general, "and I am writing to you as a relative of Liliana Rivera Garza, who was murdered on July 16, 1990." It's been twenty-nine years. Twenty-nine years, three months, and two days since Liliana was murdered by an abusive ex-boyfriend. Inspired by feminist movements across the world and enraged by the global epidemic of femicide and intimate partner violence, Cristina embarks on a path toward justice. Liliana's Invincible Summer is the account-and the outcome-of that quest.

In luminous, poetic prose, Rivera Garza tells a singular yet universally resonant story: Liliana is a spirited, wondrously hopeful young woman who tried to survive in a world of increasingly normalized gendered violence. Rivera Garza traces her sister's history, depicting everything from Liliana's early romance with a handsome but possessive and short-tempered man to that exhilarating final summer of 1990 when she loved, thought, and traveled more widely and freely than she ever had before.

Using her skills as an acclaimed scholar, novelist, and poet, Rivera Garza collected and curated evidence-handwritten letters, police reports, school notebooks, interviews with Liliana's loved ones-to document her sister's life. Through this remarkable and genre-defying memoir, she confronts the trauma of losing her sister and examines how this tragedy continues to shape who she is-and what she fights for-today.
