War of the Living - The Fall, #3

In the early days after causing the end of the world, Kell McDonald was just trying to survive. Time passed, and along with others, a new world grew. Society began to be rebuilt. Years have passed since the mutated organism known as Chimera caused the dead to rise, and on the ashes of the old world, terrifying new forces have come into play. No longer simple mindless beasts, some of the undead have evolved, becoming stronger, smarter, and more dangerous than ever.
They are nothing compared to the looming storm of living people, however, as a nation of starving men and women descend on Kell's new home to threaten everything he has grown to love.
