Outnumbered Volumes 1-6, The Zombie Apocalypse Series

I don't know where to begin because I don't know for sure where they began. Some say it started with the black magic of witch doctors in Africa, others insist it was Haitian Bokor sorcerers and their curses. Still others claim it was a virus that occurred naturally. Before world wide communications and then USA internal communications and media shut down, there were rumors the virus was developed by Muslim religious fanatics. Maybe that's why those western Asian countries were affected first and their populations annihilated first. But then there were also religious zealots here who professed the very God they worshiped unleashed the Zombie on all of us because of our greed and corruption. I'm not a religious person, never was, but I find it hard to believe any "God" that is revered by large numbers of followers would wipe out an entire planet for the sins and atrocities of a few. But after what I've seen and been through, what do I know?
