Angels. Demons. Giant Zombies. Things have changed. Ever since returning through the Storm of Skulls to the present day, Joe, Billie and August have discovered the world they now inhabit, is not the world they left behind. The zombie threat has evolved to gargantuan proportions. Now aided by giant undead-massive monsters with phenomenal strength and power, with deadly appetites just as vast-the zombie population moves to devour any and all life. Separated from his friends, Joe learns that not all hope is lost for humanity when he meets, Tracy, a woman who exudes a strength to rival his own. Tracy brings him to the Hub, an underground sanctuary where life continues in a dead world, but his thoughts linger on his missing friends. August and Billie have problems of their own, and soon learn the same plight that affected a past friend of theirs now affects many: zombies with shapeshifting capability. Now, anyone is suspect. Yet even with this newfound knowledge, more is heaped upon them when the agenda of the undead is revealed and humanity is the one caught in the crossfire. A war is raging, one between angels and demons, monsters and man. And it's only escalating.
