Leaving behind her husband and their baby daughter, a writer gets on a flight for a speaking engagement in Reno, not carrying much besides a breast pump and a spiraling case of postpartum depression. Her temporary escape from domestic duties and an opportunity to reconnect with old friends mutates into an extended romp away from the confines of marriage and motherhood, and a seemingly bottomless descent into the past. Deep in the Mojave Desert where she grew up, she meets her ghosts at every turn: the first love whose self-destruction still haunts her; her father, a member of the most famous cult in American history; her mother, whose native spark gutters with every passing year. She can’t go back in time to make any of it right, but what exactly is her way forward?

Unrelenting drought has transfigured Southern California into a surreal, phantasmagoric landscape. With the Central Valley barren, underground aquifer drained, and Sierra snowpack entirely depleted, most “Mojavs,” prevented by both armed vigilantes and an indifferent bureaucracy from freely crossing borders to lusher regions, have allowed themselves to be evacuated to internment camps. In Los Angeles’s Laurel Canyon, two young Mojavs squat in a starlet’s abandoned mansion. But when they cross paths with a mysterious child, the thirst for a better future begins.
