The living fear the dead, and the dead fear grandma.

Margaret McDaniel is a stand-up citizen; she pays her taxes, donates when she can, and is in the church pew every Sunday. She was a great wife, still is a great mother, but most of all, she is an excellent grandmother. Now that her husband has passed on, all she wishes to do is spend a few more good years with her granddaughter. That is... until the zombie apocalypse decided to happen.
With a horde of zombies threatening the well-being of her family, she has no option but to show them the righteous end of her double barrel.
