This may be the most insightfully reflective and emotionally expressive book on mountain climbing that I’ve ever read (and I’ve read many). It’s extremely well written, is full of creative turns of phrase, and includes many engaging descriptions of fascinating people and places and situations. I got choked up at times, sometimes laughed out loud, and at other times, simply couldn’t put this book down. But I still found myself too often frustrated due to not being able to fully visualize Greg Child’s descriptions of his climbs. He used far too much insider language without explanation regarding the geographic features of mountains and regarding climbing gear and techniques. If I hadn’t previously read so many other mountain climbing books, I’d have felt even more confused. This book deserved a glossary since Greg Child clearly didn’t want to upset the pace of the book with technical explanations. And his pacing in his storytelling is quite good — except for the times when I kept wishing that I knew what he was talking about.
