He keeps a city by force. She keeps his humanity by accident.

When Sera Duvall witnesses a syndicate killing, she's dragged to the cliff-top fortress of Cassian Blackwell -- the man Eden Harbor calls the Devil. He offers protection with terms she hates: silence, obedience, and a door that's never truly locked.

But rivals closing in don't want justice. They want leverage. And Cassian has already decided what Sera is to him: non-negotiable.

As war ignites across the harbor -- burned docks, bought judges, vanished drivers -- Sera learns the truth: her last name is carved inside the feud tearing the city apart. Cassian can keep her safe. He can't keep his hands clean. And when the trap finally springs, he'll make the one move that saves her... and shatters her trust.
