You're from a family of contract killers. Your smartass little brother gave your mom the finger and bolted. Bring him home. Or leave with him.

In an alternate world where assassins are the elite and ancient mercenary dynasties rule society like kings, the Argent family stands apart. Their name is a symbol of power and fear. Their contracts cost a fortune, and any target chosen by an Argent is already doomed.

Felix Argent, the clan’s nineteen-year-old heir, has been called “the best” since childhood. With his rare white hair and red eyes—the mark of pure blood—he surpassed his elder brothers in talent and skill. But instead of becoming the family’s pride, Felix turned into its curse. Sharp-tongued, sarcastic, wearing a defiant smirk and thirsting for freedom, he rejects the authority of his manipulative mother and the control of his elder brother, openly defying tradition.

After a scandalous break with his family, Felix leaves the Argent mansion and throws himself into street life: illegal races, underground brawls, reckless parties. But in a world where blood is currency and the past always hunts you down, it is not so easy for an Argent heir to escape his own name.
