The Mermaid and the Shadow Prince. The Moonfall Kingdom, #4

A prince without a shadow. A mermaid guarding an ancient secret. A love that could unite two worlds-or awaken the darkness beneath them both. Prince Dorian of Selvarin has lived his entire life beneath the weight of an impossible prophecy. Born without a shadow, he has endured whispers, suspicion, and the fear that he is destined to bring ruin to his kingdom. When the sacred Moon Pearl is stolen and a mysterious young mermaid is captured near the ancient sea caves, Dorian is ordered to retrieve both the thief and the priceless relic.
Instead, he discovers a truth buried beneath the waves. Nerissa is no criminal. She is a Guardian of the forgotten underwater kingdom of Thalassar, where an ancient seal has protected both land and sea for a thousand years. Now that seal is failing, the Black Tide is spreading through the oceans, and a powerful enemy known as Lord Malrec is closer than ever to unleashing a darkness that could consume the entire world.
As Dorian and Nerissa journey into the breathtaking ruins of a lost civilization, old enemies become unlikely allies, family betrayals come to light, and Dorian must decide whether reclaiming the shadow stolen from him as a child is worth risking everything he loves. Filled with breathtaking underwater cities, ancient magic, unforgettable sea creatures, thrilling battles, slow-burn romance, family secrets, and epic fantasy adventure, The Mermaid and the Shadow Prince is the enchanting fourth novel in The Moonfall Kingdoms-an interconnected romantasy series where each standalone love story reveals another piece of a world-changing mystery leading to one unforgettable finale.
