Blood Oath of the Hamptons is a high-stakes psychological thriller set within the Vanderbilt dynasty, where a dead patriarch's final will forces seven heirs into a thirty-day trial of "virtue"—with thirty billion dollars at stake. Sage Moreau, a mysterious art authenticator, enters the game as an outsider, only to uncover that the competition is a trap. As heirs are systematically eliminated through a network of remote-controlled micro-injectors embedded in contact lenses—a technology designed by the reclusive genius Jasper Vanderbilt—Sage discovers her own past is entangled with the family's darkest secret: the Callahan Estate fire that killed her family twenty years ago. With each death, she peels back layers of fraud, hidden accounts, and staged charity scams, forcing a reckoning with Helena, Dorian, and the executor Carter Blackwood. As the countdown nears zero, Sage must choose between vengeance and justice—and decide whether to shatter the Vanderbilt legacy or inherit its poisoned crown. An electrifying saga of power, trauma, and moral choice.
