As a quirky and awkward genius, Willow Chance has never found it easy to relate to others, except the patient, loving parents who adopted her when she was a baby. But now they have died in a car crash, and Willow is left without anyone to step in and care for her. Yet somehow she manages to push through her grief and bring together a fascinatingly diverse surrogate family for herself: her underachieving guidance counselor, Dell; a struggling nail salon owner named Pattie and her two teenaged kids, outspoken Mai and sullen Quang-Ha; and a taxi driver named Jairo who believes that Willow just may be his guardian angel. Together, this unlikely group gives Willow the one thing she needs most—a place to be herself.
