Tess Goodwin's life in rural Iowa is sheltered and uncomplicated. Although she chooses to spend most of her free time playing chess with her best friend Zander, the farm-boy from next door, her skills as a bovine midwife and tractor mechanic ensure that she fits in with the other kids at West Hancock High. But when her veteran father reenlists in the Army, moving her family halfway across the country to North Carolina, Tess is forced out of her comfort zone into a world she knows nothing about.

Tess approaches the move as she would a new game of chess, plotting her course through the unfamiliar reality of her new life. While heeding Zander's long-distance advice for making new friends and strategizing a means to endure her dad's imminent deployment to the Middle East, she quickly discovers how ill-equipped she is to navigate the societal challenges she encounters and becomes convinced she'll never fit in with the students at her new school.

When Leonetta Jackson is assigned as her mentor, she becomes Tess's unexpected guide through the winding labyrinth of cultural disparities between them, sparking a tentative friendship and challenging Tess to confront her reluctant nature. As the pieces move across the board of her upended life, will Tess find the acceptance she so desperately desires?
