When Lana and her father return to their seaside hometown to help clear the debris of a big storm, Lana remembers how much she's missed the ocean — and the strong, reassuring presence of her aunt. As Lana explores the familiar beach, she discovers something incredible: a colony of aquicorns, small magical seahorse-like creatures that live in the coral reef. Lana rescues an injured aquicorn and cares for it with the help of her aunt, who may know more about these strange creatures than she's willing to admit. But when a second storm threatens to reach the town, choices made many years ago about how to co-exist with the sea start to rise to the surface. Lana realizes she will need to find the strength to stand on her own, even when it means standing up to the people who she has always relied on to protect her.

In the co-operative game The Aquicorn Cove Board Game, 2-4 players take on the roles of members of a small fishing village struggling to survive while maintaining a balance with the natural world. To win, the villagers must feed and grow their village, while helping to restore the health of the reef and aquatic ecosystem. The villagers are fortunate, though, and the waters of their cove are home to the beautiful and benevolent aquicorns, as well as the wondrous reef guardian Aure, who can help them both to understand the impact humans are having on the environment and to save the village.
