Evelyn Foster has always felt like an outsider in her own life. Haunted by vivid dreams of burning palaces and blood-stained oceans, and bound to a mysterious silver necklace that pulses with unnatural power, she hopes a fresh start in a sleepy Italian coastal town will bring peace. But the shadows there know her name. When she crosses paths with the dangerously captivating Blackwell twins — the fierce and possessive Xander and the charming, calculating Xavier — an irresistible soul-deep bond awakens. They are hybrid princes feared across the supernatural world, and they know far more about her than they admit. As hunters close in and ancient kingdoms stir, Evelyn discovers she is the forbidden hybrid daughter of a Vampire King and Mermaid Queen — the Lost Queen of a deadly prophecy. A prophecy that demands she choose: merge the human and supernatural worlds forever… or destroy half of all magic and immortal bloodlines to bring peace. With enemies on every side and her heart torn between two powerful mates (and more bonds awakening), Evelyn must decide if she will be the savior… or the blade that ends everything. She was never meant to be found. But the world has been waiting for Their Lost Queen.
