Y/n Grey has spent her entire life in a fog-covered harbor town where the sea feels more like home than land ever has. When a violent storm uproots an old tree behind her house, she discovers a buried box containing two seal skins—one belonging to the mother who vanished years ago, and one belonging to her. The discovery unravels everything she thought she knew. As old harbor legends prove true and secrets buried beneath the tides begin to surface, y/n is forced to confront a question that has haunted her family for nearly two decades: What really happened to her mother on the night she disappeared? Caught between two worlds and drawn ever closer to the sea’s call, y/n must uncover the truth before the ocean claims the answers forever.
