A stunning coming-of-age novel about friendship, mothers and finding one's way in the world by the New York Times bestselling author of THE BOOK OF RUTH and A MAP OF THE WORLD.

Seventeen-year-old Phoebe was never interested in her birth family. But on the cusp of her high school graduation, her adoptive mother, Greta, insists on a visit to meet her biological parents and siblings. The encounter is a jolt, a revelation that derails Phoebe.

With the help of her best friend, Luna, Phoebe runs away --- as far as their friend Patrick O’Connor’s chaotic home, where she hopes to go unnoticed among his 13 siblings. What begins as an adolescent rebellion soon spirals into a whirlwind of transformation and self-discovery.

As Phoebe grapples with her shifting identity, she must navigate the tumultuous road out of girlhood and chart a new and unknown course.
