Bo knows she should go. Years of rain have drowned the city, and almost everyone else has fled. Her mother was carried away in a storm surge, and Bo has been alone ever since. She is stalled: an artist unable to make art, a daughter unable to give up the hope that her mother may still be alive. 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. Mia can be prickly, but they forge a connection deeper than any Bo has had with a client. Then Mia’s health turns, and Bo determines to honor their disappearing world and this woman who has brought her back to it.
