He betrayed his blood to protect his soul. But nothing prepared him for her.

Aaron was born into the ruthless world of the Swiss mafia—raised to be a killer, trained to be a leader, and destined to obey the legacy carved in blood. But Aaron doesn't play by the rules. When he turns his back on his powerful family and aligns with their most dangerous enemies, he crosses a line no one comes back from.

Now a traitor in the eyes of his own blood, Aaron finds unexpected honor among the rival mafia—brothers not bound by birth, but by loyalty. Torn between a past he can't erase and a future built on vengeance, he lives a double life in the shadows.

Until she returns.

Cecília, the sweet, innocent daughter of a powerful ally. The one woman Aaron swore he'd never touch. She's clumsy, beautiful, completely off-limits—and the only person who's ever made him feel human. But Cecília isn't a girl anymore. And she's about to stumble into a world where innocence is a liability... and love is a death sentence.

In a world of loyalty and betrayal, power and passion, Aaron must choose between the family he was born into... and the family he would die for.
