Twelve-year-old Natalia Rose Baleine Gallagher loves possibilities: the possibility that she’ll see whales on the beach near her new home, the possibility that the transgender boy she just met will become her new best friend, the possibility that the paparazzi hounding her celebrity father won’t force them to move again. Most of all, Nat dreams of the possibility that her faraway mother misses her, loves her, and is just waiting for Nat to find her.
But how can Nat find her mother if she doesn’t even know who she is? She abandoned Nat as a baby, and Nat’s dad refuses to talk about it. Nat knows she shouldn’t need a mom, but she still feels like something is missing, and her questions lead her on a journey of self-discovery that will change her life forever.
