Top words in top selling books

Last year I wrote an article showing the Opening paragraph of top selling books. A while ago I read an article that talked about the top words in top selling books. I've lost that article so I decided to use my data mining skills and make a similar research on my own. The books I've included are a few of the top selling books from the last article:

• A tale of two cities
• And then there were none
• The Hobbit

But since all of the top selling books are not available in the correct format needed to analyze the words, I've also included:

• The Bible
• Alice in wonderland
• The Engineer (which is my own biography book on the entrepreneur Elon Musk)

This is the result:

Alice	Two cities	Hobbit	And then	Bible	Engineer
the	the	the	the	the	the
and	and	and	a	and	to
to	of	of	of	of	a
a	to	to	to	to	and
she	a	a	and	that	of
of	in	he	he	in	in
it	his	in	was	he	was
said	it	was	said	shall	he
it	that	they	I	unto	Elon
in	I	it	it	for	that

But, as you can see, most of the words in the results above are so-called stop words, so I've also tried to see what happens if these words are removed. This is the result:

Alice	Two cities	Hobbit	And then	Bible	Engineer
said	said	said	said	shall	elon
alice	mr	bilbo	lombard	unto	said
little	lorry	dwarves	blore	lord	car
know	man	came	vera	thou	tesla
like	defarge	like	armstrong	thy	like
went	little	long	rogers	god	company
thought	time	thorin	mr	said	electric
queen	hand	time	know	ye	rocket
time	miss	great	went	thee	space
did	know	did	little	man	didnt

If I recall that old article I read on the top words in top selling books, I think the words were "and" and maybe "but." Anyway, it was interesting to see that the words in my own book matched almost all of the words in the other top selling books. But I think we will need more books to come up with any real conclusions.

Bonus!
As a bonus, I've also calculated the average words per sentence in each book. This is the result:

• Alice: 27
• Two cities: 18
• Hobbit: 20
• And then: 9
• Bible: 28
• Engineer: 20

...and average length per word:

• Alice: 4.09
• Two cities: 4.33
• Hobbit: 4.17
• And then: 4.21
• Bible: 3.94
• Engineer: 4.46
