On Blue Star Island there is a town called Starrington where thirteen year old Tenley lives with her Uncle Chase and her Aunt Tara. Not too far away from them lives a boy named Elias, who has known Tenley since they were little. The question of where Tenley's parents have gone missing thirteen years ago is still a mystery, that is, if they're even alive. Tenley, along with her lifelong friend Eli and her Uncle Chase set off on an adventure to find her lost parents. With a ship she never knew she had, Tenley grabs the wheel and the trio sails off the island and into the dangerous waves of the seas.
