Book 2 of the Judgment Day series. The zombie plague has decimated the world. Zombies have mutated into breeding, animalistic killers, homo mortuus venator, the hunting dead. The military, instead of helping the survivors, use the blood of the immune, to create Blue Juice, a temporary vaccine. Jeb Stone managed to retrieve his wife from the clutches of the Major in San Diego and, with some friends, began a new life in the glass dome habitats of Biospehere2 in Oracle, Arizona. Now, they face a new threat, betrayal from within, and an old one, the Major seeking revenge.
