Like everyone else in Palm Springs, Gish idolizes her smart, beautiful, kind older sister. Even their parents compare Gish unfavorably to Gloria -- threatening to send her to boarding school once the more perfect sister leaves for college. But Gloria has an unwavering love for Gish, even if that connection belies a weariness with her own accomplishments. Wanting a better life for her overlooked sibling, Gloria teaches Gish how to talk to boys, embrace her femininity, and finally develop a life of her own. And just as life is looking up for Gish, Gloria meets a handsome, mysterious boy. Obsessed with the stranger, Gloria closes off her life to her sister -- then disappears without a trace. A police search yields nothing. Their father’s manic investigation proves fruitless. And their already star-struck mother becomes increasingly lost in daydreams of the celebrities who partied in their house decades ago when the town was a Hollywood getaway. Untethered from the weight of her sister’s presence -- but also missing her sister’s love -- what will Gish do with this new terrible freedom, with this sense she could become anything?
