In a world where most people hide their shadows, Cole Blackwell and Mara Eldritch recognize something familiar in each other's darkness. Cole-wealthy heir, renowned artist, and calculated killer of fourteen men-meets Mara after she narrowly escapes "The Beast of the Bay," a serial killer obsessed with them both. Behind Cole's refined taste and impossibly handsome exterior lies a coldness formed in childhood. Mara, a struggling artist with extraordinary talent, carries the scars of unimaginable abuse from her drug-addicted mother and a parade of violent boyfriends. When Cole takes Mara into his seaside mansion, ostensibly for protection, he recognizes in her a kindred spirit-someone who might understand rather than recoil from his darkness. Their relationship begins with Cole holding all the cards: wealth, security, connections. Yet as they grow closer, something unexpected happens. Cole discovers he genuinely cares about someone else's happiness separate from his own desires. Mara finds herself falling for a man who sees her completely, despite knowing his capacity for violence. What starts as a predator-prey dynamic evolves into something far more complex-a dance between two damaged souls who find in each other what the world could never give them: acceptance without judgment.
