Left for Dead by Jori Reeves

Celestia Moon lives in the shadows. It's never stopped her from achieving her next big dream. She helped her best friends, Maurice and Sadie, by signing over Crescent Bar Tavern. She's come a long way from the small seaside town, where she grew up as a tavern wench in 1412.

When she finds their gorgeous grandson, London Washington, outside her front door, she feels a protective spark for him. Although someone had stabbed him multiple times. "What trouble do you bring if healing you turns you from human to vampire?" she asked the near-dead human.
