Blood Relations

Renee lives in a house where ghosts are the norm. Although they're really technological artifacts, according to her cousin Gil, who's not really there. Renee leads an unusual life, and develops a unique talent for moving through time and space. When the local vampires face a deadly threat, she uses her abilities in their defense, while finding it difficult to resist their seductive allure.

Fair warning: Although this is a coming-of-age story with some erotic elements, it is not a romance.
