If you like Sunshine by Robin McKinley

Sunshine by Robin McKinley: "There are places in the world where darkness rules, where it's unwise to walk. But there hadn't been any trouble out at the lake for years, and Sunshine just needed a spot where she could be alone with her thoughts. Vampires never entered her mind. Until they found her."
