It's all they've heard since a schoolmate of theirs drowned a year ago. Pao is embarrassed to admit that she has been told to stay away for even longer than that, because her mother is constantly warning her about La Llorona, the wailing ghost woman who wanders the banks of the Gila at night, looking for young people to drag into its murky depths. Hating her mother's humiliating superstitions and knowing that she and her friends would never venture into the water, Pao organizes a meet-up to test out her new telescope near the Gila, since it's the best stargazing spot. But when Emma never arrives and Pao sees a shadowy figure in the reeds, it seems like maybe her mom was right. Pao has always relied on hard science to make sense of the world, but to find her friend she will have to enter the world of her nightmares, which includes unnatural mist, mind-bending monsters, and relentless spirits controlled by a terrifying force that defies both logic and legend.
