Genetically altered with the DNA of the predators of the earth. The wolf, the lion, the cougar, the Bengal; the killers of the world. They were to be the army of a fanatical society intent on building their own personal army.Until the world learned of their existence. Until the council lost control of their creations, and their creations began to change the world.Now, they're loose. Banding together, creating their own communities, their own society, and their own safety, and fighting to hide the one secret that could see them destroyed.The secret of mating heat. The chemical, biological, the emotional reaction of one Breed to the man or woman meant to be his or hers forever. A reaction that binds physically. A reaction that alters more than just the physical responses or heightens the sensuality. Nature has turned mating heat into the Breeds' Achilles Heel. It's their strength, and yet their weakness. And Mother Nature isn't finished playing yet.Man has attempted to mess with her creations.
