The students at Lizzie’s high school are notoriously terrible at breakups. Forget awkward conversations—they’re dumping each other via text. Inspired by the terrible breakups around her, sixteen-year-old Lizzie, strapped for cash and itching to go on the school’s band trip to NYC, teams up with her best friend, Willa, to create a genius business: personalized gift baskets—breakup baskets—sent from dumper to dumpee. The Goodbye Girls operate in secret, and business is booming. But it’s not long before someone begins sabotaging The Goodbye Girls, sending impossibly cruel baskets to seemingly random targets, undermining everything Lizzie and Willa have built and jeopardizing their anonymity. Soon family, friendship, and a budding romance are on the line. Will Lizzie end up saying goodbye to the business for good?
