Nico Russo has spent years surviving the family that treats him like an embarrassment—and secretly becoming “Ghost,” one of the most dangerous hackers on the dark web. When he steals and encrypts a ledger capable of destroying New York’s most powerful crime families, ruthless billionaire Julian Vance storms the Russo estate to recover it. Instead of killing Nico, Julian takes him captive and confines him inside his Manhattan penthouse. Nico refuses to become anyone’s obedient prisoner. Every order becomes an argument. Every threat becomes a dare. And every confrontation pushes the two enemies closer to a line neither of them should cross. But when a conspiracy inside both families puts Nico in an assassin’s sights, Julian’s need for control turns into something far more dangerous: devotion. Forced into a marriage contract and trapped between loyalty, revenge, and desire, they must decide whether they can trust each other before the ledger exposes a truth powerful enough to destroy them both.
