Ascension

Alison Wells is no ordinary woman. Born with supernatural powers, she can never make love to a man without putting him in grave danger. But when her special vision reveals a glorious muscled man soaring overhead on mighty wings, she feels an overwhelming attraction she cannot resist—even as he tells her: "I have come for you. Your blood belongs to me."
Kerrick is a vampire and a warrior who has fought his hunger for a woman's love for the past two hundred years. As a Guardian of Ascension, he is sworn to protect Alison from the death vamp armies who crave her blood and her power. But Kerrick has cravings of his own—a forbidden longing to open his heart and veins to Alison. To share his blood...satisfy his thirst...and seal their fates forever.
Ascension is the first in Caris Roane's paranormal romance series that Romantic Times calls "a series with epic potential."
