An addictive dark romance about a vigilante with blood on his hands and the woman he'll burn the world down to keep.

Cassius Ashenheart isn't looking for redemption. He's the man people call when justice fails—a weapon forged by his family's sins. His world is brotherhood, violence, and brutal secrets. Love doesn't fit a life built on quiet retribution.

Melinda Westbrook edits fictional killers for a living. Real danger stays safely on the page—until a wrong-number text and a terrifying encounter force a stranger to step in and pretend to be her husband.

Cassius should walk away. Instead, one act of protection turns into late-night messages, a dangerous bond, and a marriage that blurs the line between safety and obsession. The more he shields Melinda from the monsters in his world, the more he wants to keep her—close, claimed, and completely his. But when the threat circling her ties back to his own bloody past, he has to decide what he's willing to sacrifice.

His brothers. His code. Or the woman who makes the killer in him feel almost human.
