Ingrid Rojas Contreras' maternal grandfather, Nono, was a renowned curandero, a community healer gifted with what the family called “the secrets”: the power to talk to the dead, tell the future, treat the sick and move the clouds. And as the first woman to inherit “the secrets,” Rojas Contreras’ mother was just as powerful. Mami delighted in her ability to appear in two places at once, and she could cast out even the most persistent spirits with nothing more than a glass of water. While living in the U.S. in her 20s, Rojas Contreras suffered a head injury that left her with amnesia. As she regained partial memory, her family was excited to tell her that this had happened before. Decades ago, Mami had taken a fall that left her with amnesia, too. And when she recovered, she had gained access to “the secrets.”

Seven-year-old Chula and her older sister, Cassandra, enjoy carefree lives thanks to their gated community in Bogotá. But the threat of kidnappings, car bombs and assassinations hover just outside the neighborhood walls, where the godlike drug lord Pablo Escobar continues to elude authorities and capture the attention of the nation. When their mother hires Petrona, a live-in-maid from the city's guerrilla-occupied slum, Chula makes it her mission to understand Petrona's mysterious ways. As both girls' families scramble to maintain stability amidst the rapidly escalating conflict, Petrona and Chula find themselves entangled in a web of secrecy that will force them both to choose between sacrifice and betrayal.
