Sam Parker is a vampire with a gift so strong and substantial that she is invited to partake in a test for a place in the Grand High Master Vampire's private army. She finds that not only has the army never included a woman, but it has never included a Svente vampire; a breed that is regarded by the super strong Pagori breed and the hypnotically beautiful Keja breed to be too tame and human-like.
When Dr. Stephen Wallace, a fertility specialist from Sydney Australia, is approached by his brother and sister-in-law for help conceiving a child there is no way he can refuse. Since they have already exhausted all the possibilities modern medicine can provide, Stephen turns to his skills as a shaman for alternative solutions. His search leads him to Las Vegas, Nevada on a slim lead to capture a succubus who he hopes has the power to help.
