As a book, I found it somewhere between mediocre and dreadful, more towards the latter if you don't care at all about so-called "pro" snowboarders.
Once the narrative switched to the SME multi, it became far more compelling.
That information might have been based almost entirely on Ken Wylie's book, but since that book sounds even worse, a retelling of his account might be better than the original source material.
So, a limited endorsement: if you're interested in how such a scenario could unfold, with two fully certified professional guides (i.e., not just bro guides), then definitely read (or listen) to this.
