Half-heartedly, she allows her cousin to plan for her escape—but as the departure day approaches, she finds a note slipped under her door from Mia, an elderly woman who lives in her building and wants to hire Bo to be her caregiver. Suddenly, Bo has a reason to stay.

Even the boy’s slightly stoned uncle, Bob Alexander, who is supposed to be watching him for the summer, notices the change. Nathaniel is happier, more confident—tanner, even.
