I slept with a stranger whose face I never saw. I only knew three things about him. He was rich. He was dangerous. And he paid enough money to save my mother’s life. I thought it would be a one-night secret. Until I discovered I was pregnant. With one baby… and two possible fathers. Because the man I slept with wasn’t just one man. He was two identical twin brothers. One is a ruthless Mafia Alpha who rules the werewolf underworld. The other is a cold billionaire tycoon who controls half the city. Same face. Same blood. Same DNA. But only one of them is my fated mate. The other? He is the man who would burn the world down before letting me belong to his brother. The twins have hated each other since birth. And now I am carrying the child that could decide their war. Because in the world of Alphas, a baby with two possible fathers is not just a scandal. It is a weapon. And my unborn child might become the most dangerous heir the pack has ever seen.
