Natasha Carter has one rule: never get involved with dangerous men. After losing everything, she accepts a live-in nanny position at the Blackwood Estate, caring for six year old Lyra the bright, stubborn niece of the city's most feared mafia boss. Josh Moretti doesn't trust strangers. Especially not the woman now living under his roof.

One signature. One contract. One wedding. The man she loved sold her to the most feared Mafia King in Europe to settle his debt. Now she belongs to Enzo Moretti cold, ruthless, and powerful enough to make entire cities kneel. Her only goal? Escape. But the monster the world fears isn't the man she meets behind closed doors. Instead of chains, he gives her freedom. Instead of cruelty, he offers protection. Instead of demanding love... he quietly falls first. Yet on the very day they exchange vows, hidden assassins strike. Someone wants the Mafia King dead. And someone is willing to kill his bride to make sure it happens. In a world built on blood, loyalty, and betrayal... Can a contract become forever? Or will their love end before it truly begins?
