Slightly off topic, but I first heard of Green Boots in the book The Climb. I picked it up completely randomly from a used book store six states away from home and wow what a find! It is a riveting story start to finish and I recommend it to everyone who is looking for a great read. My partner got her hyper fixation on high altitude mountaineering from it despite having no interest in ever actually climbing a mountain herself from reading it.
If you haven’t yet I highly recommend checking it out.
I've only read Into Thin Air, but that book makes Boukreev (author of The Climb) seem like an unreliable narrator. I have zero interest in high altitude mountaineering (I prefer lower altitude rock climbing) but I should probably check out The Climb to get both sides.
