On the remote, sun-drenched island of Isla del Sol, three best friends-Mira, Kalani, and Sienna-stumble upon an ancient lagoon hidden deep within a mystical coconut grove. Under the glow of a rare Azure Eclipse, the waters enchant them, changing their fate forever. By day, they are normal teenagers exploring island life, but under moonlight, they transform into powerful sea beings.
But they're not alone. A secret oceanic tribe watches from the depths, and a mysterious force threatens to awaken something ancient beneath the waves. As they navigate friendships, romance, and the call of the ocean, they must uncover the truth about their transformations-before it's too late.
