A Seal. A Circle of Friends. A Special Kind of Magic.

Twelve-year-old Ellie didn't expect her life to change when she moved to her late grandmother's coastal homestead in Whitneyport, Maine. But with each crashing wave and whispered memory on the shore, she uncovers something extraordinary about her family, her community, and the fragile balance of the natural world.

In a town where tradition runs deep and change is met with silence, Ellie must find her voice. With the help of a misfit circle of friends, a mysterious harbor seal, and the enduring magic of her grandmother's spirit, she steps into her power as a young climate activist.

Set against the wild beauty of the Maine coast, The Secret of the Catapus is a richly told coming-of-age tale that blends environmental urgency with heartfelt storytelling, humor, and a touch of magical realism.
