At twenty-six, apprentice baker Mia West has her entire life planned out: a Craftsman cottage in Seattle, a job baking at The Butter Emporium, and her first love—her boyfriend, Ethan—by her side. But when Ethan declares he “needs some space,” Mia’s carefully planned future crumbles.

Feeling adrift, Mia joins her vivacious housemate Rosie on a humanitarian trip around the world funded by a reclusive billionaire. Along with a famous grunge rock star, a Rwandan immigrant, and an unsettlingly attractive Hawaiian urban farmer named Kai, Mia and Rosie embark on the adventure of a lifetime.

From the slums of Mumbai to a Hungarian border camp during the refugee crisis, Mia’s heart is challenged and changed in astonishing ways—ways she never could have imagined. As she grapples with how to make a difference in a complicated world, Mia realizes she must choose between the life she thought she wanted and the life unfolding before her.
