Gwyn's family has traveled from Vancouver to Nova Scotia, where they plan to make their new home in Mahone Bay. Gwyn doesn't care for the idea at all and, in fact, has sulked from the west coast to the east, unlike her little sister, Linden, who's caught up in the adventure. Gwyn only agreed to make the trip because her parents bribed her with three promises to be filled when they reached their destination. Despite her unease, Gwyn begins to grow into this new place, and as the three promises are slowly delivered, she comes to agree with Linden that this is indeed "My Home Bay".
