From Horror World Reviews:

The venerable Christmas carol, once the domain of the charitable and the merry has now been forever tainted by the stench of the rotting and the cadaverous. The results could be called sacrilegious, offensive, and in bad taste. They could be called that, but not by me. I find them hilarious and chances are, if you’re reading this, you will to.

Author Michael P. Spradlin has taken thirty of the most beloved carols and popular Christmas related tunes and has changed the words to reflect the ever growing Undead American point of view. Luckily zombies are atheists (who knew?) and decided to skip the traditional, Christian Christmas songs like “Silent Night”, “O Come All Ye Faithful” and the like. A wise choice as no one needs the image of baby zombie Jesus eating brains in the manger. Oh wait, forget I said that.
