"A once-every-few-years reading experience."—Mary Beth Keane, New York Times bestselling author of Ask Again, Yes

"Coster portrays her characters’ worlds with startling vitality. As the children fall in lust and love, grapple with angst and battle the tides of New South politics, Coster’s writing shines"—New York Times Book Review

From the author of Halsey Street, a sweeping novel of legacy, identity, the American family—and the ways that race affects even our most intimate relationships.

In the Piedmont of North Carolina, two families’ paths become unexpectedly intertwined over twenty years. Jade and Lacey May are two mothers determined to give their children the opportunities they never had. After a harrowing loss, Jade wants to hand down the tools her son, Gee, will need to survive in America as a sensitive young Black man. Meanwhile, Lacey May, having left the husband she loves, strives to protect her three half-Latina daughters from their charming father’s influence.
 
When a county initiative draws students from the largely Black east side of town into a predominantly white high school on the west, each mother stands on different sides of the integration debate. Gee meets Lacey May’s daughter Noelle during the school play, and their families begin to form deeply knotted, messy ties that will shape the trajectory of their adult lives. And their mothers make choices that will haunt them for decades to come.
 
What’s Mine and Yours is an expansive yet intimate multigenerational tapestry of motherhood, identity, and the legacies we inherit. It explores the unique organism that is every family: what breaks them apart and how they come back together.
