The Billionare's Secret Heir

I had given up on love until I met the steamy hot and rich billionaire playboy, Mark Mogul. My life's plan was to take care of my only daughter until he told me he loved me. I believed him but he broke my heart when he decided to do his family's bidding–marrying Vanclair heiress, Emily Vanclair.

When my daughter gets into an accident and he rushes in to help, he discovers he is a match for her blood transfusion. Only I know this secret that I had been hiding for years, but it wasn't intentional, I made a mistake.

Now he is demanding to know the truth. But how can I tell him, knowing his fortune is at stake and his family will never accept me or my child?
