A Farmer?!

In a dark foggy library, a man was having a meltdown.

Jack glanced at the mountain of books they had set aside. It was now big enough to play king of the hill!

The recent tomes they had dug out were: 

- Tone-deaf tunes for Skeleton armies sieging cities— Useless without an army. 

- Infinite Demonic Energy in the Apocalypse— Potentially deadly!

- Fantastic undead and where to find them— Undead GO?! 

- The man who threw pens at the undead— WTF?! 

- Making Eternal s̶l̶a̶v̶e̶ Friends— Perhaps?

- A Loser's Guide to Skeletons— Maybe? 

- Chicken Soup for the Soul — SPI?

- Liches of Azincourt— History? 

- Know your bones — Medical? 

- The Good Skeleton— Divine?

- Undead Life — Documentary?

- Etc. 

Hell, choosing just one each was as hard as picking between tits or ass! In an ideal world, Jack would have buried his face in all of them at once! (The books)
