With Samantha "Sam" Johnson, Dr. Jim White, a 130-year-old vampire, has the best sex of his life. It's a shame she had to be his next victim. But she had a surprise for him. As a lycan, she hunted him as he hunted her. After discovering each other's secret, they cannot resist the physical attraction. Together they hunt and reach out to others of their kind using technology to form a support group. Sam and Jim become the first lycan/vampire pair bond.As a mathematics professor and man of science, Dr. Jim rejects the ways and lore of old in favor of modern solutions that, if not acceptable to humans, allow lycans and vampires, The Subspecies, to live invisibly, because discovery is their worst fear.The Subspecies are a mutation within the human genome. No more than 700 have been alive at one time. They cannot breed with humans or within their own group, but when Sam and Jim get in a family way, a universe of possibilities opens for not only them, but all of their kind with the promise of life being more than hunting, hiding in shadows, and fruitless mating.
