It looks like the site I used to read Zen of Assembly Language: Volume I is down. You can check yourself if it is still offline https://www.jagregory.com/abrash-zen-of-asm/
In the meantime, I am hosting a mirror here. I even like to think that this mirror is slightly better because it contains a few fixes that never got merged into @jagregroy his version.
I am also hosting an epub version here.
Shoutout to Steve Gibson from the Security Now podcast for recommending this book.
