Well, I agree this is the irreverence that the Everest genre was waiting for! I laughed quite a bit, and smiled at much of it.
The Dianas (Princesses that is) expedition really tickled my funny bone the most. How inspired to take two such icons, both ludicrously unattainable for most mere mortals, and marry them. Humour is such a subjective thing, you will either love it or hate it. But don't condemn this take on Everest because of a misapprehension of what it is about. It is a cartoon book. It does actually say more about the reality of the sponsorship and money side of 'personal Everests' than all the thousands of words I have read on the subject thus far.
