Behind Europe's gilded façades lies a world where silence is power and loyalty is currency. Damian Cesarini, heir to a Venetian legacy and one of the Umbra Collective’s deadliest strategists, commands influence from the shadows, until one mistake threatens to unravel everything. When his protégé, Evie Blackstone, crosses a line in London, the Collective turns its cold gaze upon them both. To shield her, Damian must face the board’s fury, even as the Collective’s assassins, the Ghost, move in the dark. From Venice’s opera houses to London’s marble corridors, the pair navigate a ruthless chess game of deception, loyalty, and restraint. As the Council of Umbra closes ranks and old debts surface, Evie must prove she deserves the trust he has risked everything to protect. The Umbra Collective blends espionage and psychological tension in equal measure, a world of elegance and danger where love is forbidden, failure is fatal, and the only law that endures is loyalty.
