Another freebie from Severed Press - The Village of Dead Souls: A Zombie Novel
by Michael Wallace.
Killed in battle, the ancient Athenian, Prometheus, awakes inside a body that is not his, in a future world unfamiliar to him. Trapped in modern day Denver, during the annual Zombie Pub Crawl, he is surrounded by humans with their strange language of moans, and hisses. Joined by a growing number of living dead, the new arrival helps them organize into a well-organized army during the zombie uprising. Only they are not here to destroy the living, they have come to save them.
The future of the human race relies on the necromantic secrets inside the shadows of the Village of Dead Souls.
