After reading Into Thin Air I would strongly recommend reading Anatoli's book on the 1996 tragedy (here's an Amazon link to the book). It exposes a lot of the flaws from Krakauer's accounts. It's also very interesting getting Mountain Madness' side of the story.
Book about the 1996 disaster by one of the Mountain Madness guides:

I don't remember how I ended up having the book, but I've read it multiple times now. Good read. There's PDF versions floating around on the internet too.
For Russian you could look at “The Climb”https://www.amazon.com/Climb-Tragic-Ambitions-Everest/dp/0312206372
Have you read Anatoli Boukreev's <u>The Climb</u>?
Very different perspective on the events of that month.
