From the author of Oprah's Book Club pick and New York Times bestseller Nightcrawling, here is an astonishing new novel about the joys and entanglements of a fierce group of teenage mothers in a small town on the Florida panhandle.

Adela Woods is sixteen years old and pregnant. Her parents banish her from her comfortable upbringing in Indiana to her grandmother’s home in the small town of Padua Beach, Florida. When she arrives, Adela meets Emory, who brings her newborn to high school, determined to graduate despite the odds; Simone, mother of four-year-old twins, who weighs her options when she finds herself pregnant again; and the rest of the Girls, a group of outcast young moms who raise their growing brood in the back of Simone’s red truck.

The town thinks the Girls have lost their way, but really they are finding it: looking for love, making and breaking friendships, and navigating the miracle of motherhood and the paradox of girlhood.

Full of heart and life and hope, set against the shifting sands of these friends’ secrets and betrayals, The Girls Who Grew Big confirms Leila Mottley’s promise and offers an explosive new perspective on what it means to be a young woman.
