In the river delta of Bangladesh, Gabe investigates classrooms on boats, flood-adapted homes, changing channels, and communities determined to keep learning even when the physical ground moves. Rima is cheerful, practical, and impatient with the idea that a life in motion cannot also promise stability.

A message connected to the family's search asks an unexpected question: not where they should go next, but what kind of home the children want to return to.
