I wrote a book on chess

it’s called The Immortal Book. I swear it’s not a scam. I tried to couch a list of immortal world champions into one book. Each of the world champions is undisputed and each one of them is the definition of the number ten. Check it out on Amazon, The Immortal Book, by Adam Foltin. Published by Kdp.

I looked it up.

It looks like it does contain the names of some world champion chess players but it is not about the champions of chess.  

I couldn't actually tell what it was about. 

There seem to be multiple versions.  This one was $15 . The description says it is 11 pages long.

There is another version which appears different.  It is longer but $42 seems like a lot for a 29 page self published e-book.

Reading those two samples is enough to put anyone off buying it.
