Graciela is raised in the shadow of El Salvador's Izalco volcanos, dusty-kneed and bound closely to her friends. Her life changes entirely when a messenger from the Capital comes to claim her. At nine years old she has been selected to work as an oracle to the country's fearsome dictator, who believes she is a muse capable of foreseeing the future of El Salvador. Brought to the city, far from her mother and friends, Graciela is introduced to Consuelo, the sister she’s never known. Consuelo is wilful, talented and desirous, and despite their differences the girls are a small fortress within the dictator’s regime. La Matanza - the brutal massacre that tore through El Salvador in 1932 - will change their lives, and their country, forever. But neither ever gives up hope that they might be reunited once more.
