My Sister Ran Away, So I Married the Mafia King

Victoria was supposed to marry Dominic Castellano. She ran away on the wedding day. She had heard the rumors: he killed his last husband. To protect his sister and his family, Liam Watson stepped forward. He was Victoria's older brother. He was a surgeon. He wore a white suit and married Dominic himself. Liam thought it was a temporary deal. Dominic thought otherwise. He was fascinated by the man who had taken his sister's place. He was fascinated by the man who talked back, who ran, who held a knife to his throat. So Dominic made a bet. Thirty days. A fake drug. If Liam fell in love with him, his heart rate would spike and the drug would kill him. Unless Liam confessed his love and chose to stay. The marriage became a game with life as the stake. But the real danger was not whether Liam would fall. It was whether he could still choose to leave once he did.
