Though beautiful, cunning, and privileged, nineteen-year-old Mickey finds herself with a stalled modeling career, an escalating drinking problem, few friends, and next to nothing in the bank. To numb her growing despair, she spends her days frantically refreshing her Instagram feed, obsessively tracking the movements of Insta-famous model Gemma Anton. Mickey sees Gemma as a perfected version of herself. Gemma is living a seemingly perfect life: a skyrocketing career, a famous boyfriend, and adoring followers. It’s the life Mickey wants more than anything. Mickey studies every detail Gemma offers through the window of her phone, trying to absorb, mimic, the object of her growing fascination. When a chance encounter thrusts Mickey into a world of opportunity, she is met with surprising—and immediate—success. But as her online persona begins to take over, the line between reality and illusion disappears. Then suddenly, so does Gemma. Engrossing, sharp, and astute, is a shimmering portrait of infatuation, disconnection, and identity—and a dazzling introduction to a brilliant new voice in contemporary literature.
