Age of Tides (en Inglés) - Myunique C. Green

Beneath the turquoise waters of the Caribbean-bright kingdom of Lurea, every mermaid is born with a current-a power that binds them to the sea. Every mermaid except Princess Maren.

Maren has lived her life as the royal embarrassment: currentless, powerless, and barely tolerated in a palace that worships perfection. Her father, the King of Tides, rules through faith. Her mother, a human-turned-queen, clings to forbidden science to awaken what the ocean denied their daughter.

But when one desperate experiment sparks something inside Maren-something electric-the currents of the entire sea begin to fail. Suddenly, the kingdom that rejected her sees her as both weapon and prophecy, a living echo of a long-banished sea god whose storm once split the world in two.

Now hunted by her own people and pursued by the exiled merfolk of the Trench Below, Maren must decide whether to save the kingdom that never loved her...or break the ancient Covenant of the Sea forever.

A lush, emotional YA fantasy filled with coral kingdoms, Caribbean hues, and dangerous beauty, Age of Tides is perfect for readers who love House of Salt and Sorrows, A Song of Wraiths and Ruin, and To Kill a Kingdom.
