Dawn After the Night

Evangeline, Heaven's youngest battle angel, is sent to Hell as demon lord Azrael's lover to assassinate him. She finds he protects outcasts—but still kills him. Pregnant with his hybrid child, she marries human heir Nathaniel to hide her son. Three years later, at a New York gala, she discovers philanthropist Dante is Azrael, resurrected as a mob boss. He reclaims his empire—and learns she has a family.
