When a sealed federal warrant leaks and her partner is murdered, HSI agent Merritt Gage is forced onto leave just as she discovers a trafficking route running through the infrastructure of West Coast crime boss Dario Ferri.

Ferri offers evidence, a boat, and inside knowledge of an offshore staging island—but only through a lawful cross-border operation Merritt insists on building with warrants, medics, interpreters, and Mexican command rather than vengeance.

As the two negotiate a proffer, a joint rescue, and an escalating attraction, they trace the corruption upward past a respectable logistics magnate toward someone inside Merritt’s own agency.

Every step tests whether a dangerous man can genuinely cede control and whether an agent can do the work without letting grief write the ending.

Tropes: enemies to lovers, cop and criminal, forced proximity, only one bed, morally gray dangerous hero, reluctant allies to partners, reformed/redeemed criminal, grief and revenge, found family, slow-burn to explicit, consent-forward power exchange, rescue dog
