Summary
Talia heard the ocean calling. She didn't go alone.
When Talia (Malia Baker) follows a haunting pull to the sea, she brings her closest people-her sister Skyee (Ruby Rose Turner), humorous, fiercely loyal, and always ready to defend her, and Kai (Kylie Cantrall) , bold, intuitive, and unafraid to challenge the tide. What begins as a late-night search becomes a transformation none of them saw coming. The girls awaken to magic, bonded by a pearl of ancient power, mystery, and a legacy buried deep beneath the waves.
But the ocean doesn't give gifts freely.
As their powers grow and strange visions surface, the trio must navigate a world of hidden truths, elemental forces, and a destiny that threatens to tear them apart. The deeper they dive, the more they realize: this isn't just about magic. It's about who they are, who they were meant to be, and what they're willing to fight for.
A story of sisterhood, sea-magic, and the moment everything changes. Perfect for fans of elemental fantasy, emotional arcs, and mythic coming-of-age tales.
"Three girls. One tide. No turning back."
