Post-Potter depression is what many are feeling right now according to the Urban Dictionary. You know the down feeling that lingers after seven books of Harry Potter. 

The ride is over; the series is ended. 

But will Harry Potter remain? Will it become a piece of literature that will stand the test of time or will its popularity poop out and go down the pot? 

According to Wikipedia, the top eight, best-selling, single volume books of all time are: 

The Bible at 5-6 billion sales

Moa Tse Tung at 900 million

The Karan at 800 million

Xinhua Zidian at 400 million

Book of Common Prayer (numbers not available)

Pilgrim’s Progress

Foxe’s Book of Martyrs

Book of Mormon at 120 million 

There is quite a jump between the first two bestsellers from 900 million to 5-6 billion. 

I am contemplating the content of the Bible, and its enduring appeal and contribution to the content and contentment of our lives.
