The Lover's Sentinel.

They were are two vampires who have been in love for centuries. They have a special bond that allows them to share their thoughts and feelings, even when they are apart. Damien has vowed to be her sentinel, watching over her while she sleeps. He spends his nights guarding, reading her books, playing her music, and whispering his love to her. He also leaves her notes and gifts for her to find when she wakes up. Their love is eternal and unbreakable, but it also comes with a price. They can never be together in the daylight, and they have to hide their true nature from the humans who would hunt them down.
