I couldn't find an ePub of this book anywhere. I don't know if this is legal, but I made an InDesign version of it and created an ePub version.
This is my first attempt, it's certainly not perfect. Anyone is welcome to take what I've started and tweak it.
Dear Mr Stephenson and/or Publisher,
If this is not kosher, let me know via my github account. I will remove it promptly.
