Luca Bianchi learned loyalty at the end of a barrel. When his family's empire begins to fracture, his faith in the code that built it starts to crumble too. Discipline isn't just his creed-it's his curse.

But when a war abroad forces the Bianchis into new alliances, Luca finds himself tethered to Isabella, a woman who sees through his armor and refuses to bow. She's gentle where he's brutal, and fearless where he's cold. Together, they walk a line between devotion and destruction, each hit and confession drawing them deeper into a storm that will test the limits of their love-and their survival.

In the world of Dark Ties, every vow comes with a price.

And in Luca's world, mercy is the most dangerous sin of all.
