The DFIR Book Share Challenge (I made that up by the way, but it works for me)

First, hats off to those authors contributing their books to the DFIR Book Share Challenge and participating in this endeavor.

And just as important, thanks to the winners of the books who are fulfilling the challenge of passing the books along after reading them.

Everything is paid by the book authors (if they donate a book, which they have to buy and ship), and me (to buy the books authors don't donate, and shipping). The only thing that can be considered a catch is that you are limited to winning one book, ever (at least from this challenge). 

How is the winner chosen?
