Not sure how I would rate this. There were so many moments of brilliance, moments that made me gasp and want to read bits aloud to my partner. And then there were bits that I felt were overwritten and superfluous (mostly about the Old Sherpa's past). I believe this is a debut, and so my takeaway is that this author has an incredible talent which needs a little help (experience? guidance? editing?) 

It's not quite a favourite book, but one I want to keep around and return to nonetheless.
