Price of Life — David Crane

At the dawn of civilization, a prehistoric hunter finds an unusual meteorite that offers him powers of life and death and makes him an immortal. Twelve thousand years later, his descendants, inheriting the gene of immortality, are living in secret among unsuspecting humans. Able to give and take life at will, they struggle for survival across the centuries. When a group of human fanatics and evil immortals each come with their own horrific plan for world domination, other humans and immortals must join forces to stop them regardless of the cost. At stake is the survival of both races as they prepare to face the greatest challenge of their lives.
