Winner of the 2026 Maine Literary Award for Young People's Literature

Twelve-year-old Ellie Andrews didn't plan on spending seventh grade in a tiny Maine fishing village. But when her parents' marriage falls apart, she finds herself at her late grandmother's coastal homestead in Whitneyport?where the lobster boats run at dawn, the tides tell time, and a mysterious harbor seal keeps turning up wherever she goes.

Gram was the town's beloved teacher, a fierce environmentalist, and a woman with a few secrets. As Ellie finds her footing with a misfit circle of friends, navigates a teacher who refuses to believe in climate change, and tries to keep a promise to a grandmother she can still feel watching over her, she begins to understand what Gram was protecting?and why it matters more than ever.

The Secret of the Catapus is a coming-of-age story about grief, courage, and what it means to carry someone's legacy forward. It's also about a seal named Catapus, who has his own ideas about where Ellie belongs.

For readers ages 8?12 who love the ocean, animals, and stories that stay with them. For fans of Hoot by Carl Hiaasen and Island of the Blue Dolphins.
