Eleven-year-old Izzy wants her dad to act like he did before he was deployed to Afghanistan. She wants her mom to live with them at the marina where they've moved instead of spending all her time on Block Island. Most of all, she wants Piper, Zelda, and herself, the Sea Stars, to stay best friends as they start sixth grade in a new school. Everything changes when Izzy's father invites his former interpreter's family, including eleven-year-old Sitara, to move into the marina's upstairs apartment.
