It's March of 2019, and twenty-eight-year-old Jules Gold--anxious, artistically frustrated, and internet-obsessed--has been living alone in the apartment she once shared with the man she thought she'd marry when her younger sister Poppy comes to crash. Indefinitely. Poppy is a year out from a suicide attempt only Jules knows about, and as she searches for work and meaning in Brooklyn, Jules spends her days hate-scrolling the feeds of Mormon mommy bloggers and waiting for life to happen.

Then the hives that've plagued Poppy since childhood flare up. Jules's uterus turns against her. Poppy brings home a maladjusted rescue dog named Amy Klobuchar. The girls' mother--a newly devout Messianic Jew--starts falling for the same deep-state conspiracy theories as Jules's online mommies. A trip home to Florida ends in disaster. Amy Klobuchar may or may not have rabies. And Jules struggles halfheartedly to scrape her way to the source of her ennui, slowly and cruelly coming to blame Poppy for her own insufficiencies as a friend, a writer, and a sister. As the year shambles on and a new decade looms near, Jules and Poppy--comrades, competitors, permanent fixtures in each other's lives--must ask themselves what they want their futures to look like, and whether they'll spend them together or apart.

Deadpan, dark, and brutally funny, Worry is a sharp portrait of two sisters enduring a dread-filled American moment from a nervy new voice in contemporary fiction.
