Jasmine Paris inherited her father's yacht empire believing him a simple businessman—until she discovered he'd supplied vessel specs to operatives in the spy world. Now determined to uncover his secrets, she personally delivers a $80 million superyacht to Hong Kong to investigate the enigmatic Akira Takeda. What she doesn't know: the yacht carries a hidden archive worth killing for, and Circle-affiliated workers have already embedded it in the hull.

When Takeda arrives by helicopter with his dangerously capable chief of security, Masato Ishikawa, Jasmine finds herself caught between a slow-burn attraction she can't trust and a mystery she can't ignore. During the open-water trial, everything explodes into violence. As Jasmine and Masato fight to survive the attack, she realizes the assault was no accident—and that her father's "clean" drawings were anything but. In the wreckage, one truth becomes clear: the yacht carries secrets worth dying for, and in the world of the Circle, no one can be trusted completely.
