After 300 years of marriage, I'm finally pregnant with his dead lover

For 300 years, he fed me his blood every day. He said it was for the baby. Then I heard him tell his men — "She's just the vessel. Once the child is born, drain her dry." The baby in my womb wasn't ours. It was his dead lover's soul. I walked into holy fire to burn her out of me. That's when he appeared — a man who said he'd been waiting for me for three hundred years. Three centuries of lies. One blood oath.Time to collect.
