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. When a second storm threatens to reach the town, choices made many years ago about how to coexist 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.
