A Tale of Two Vampires. Dark Ones, #12.5

Time isn't always on a vampire's side. Iolanthe Tennyson has had a very bad year-her boyfriend dumped her, she got fired from her job, and her apartment is falling down. So, she's accepted her cousin's invitation to spend the summer in scenic Austria indulging in her photography hobby. There, rumors of a haunted forest draw Io into the dark woods-and to her complete stupefaction, into the eighteenth century. Nikola Czerny is a cursed man, forced to live forever as a Dark One.
But his miserable existence takes an interesting turn when a strange, intriguing woman is literally thrown into his path. More confusing, Io claims to know Nikola's daughter-three hundred years in the future. She also knows what fate-in the form of a murderous plan-has in store for him. If only she knew the consequences of changing the past to save one good, impossibly sexy vampire.
