Well, I just panned a different book and said don't waste your money so now its time to even the score.
This book is great fun. I have lots of winter camping books and do a fair amount of winter camping. Other books may have more information, but none covers all of the basics with as much humor as this one. I do alpine skiing and snowshoeing so the coverage of tele skiing wasn't of particular interest...but I still really enjoyed reading those sections, too.
It is hard to describe the authors' irreverent approach while dealing with serious (life and death) topics, but they somehow pull it off. This is really a great book to engage someone who isn't already a hard-core winter camper...so if you are, buy it for your significant other (assuming you haven't been able to get them enthused about spending a winter weekend outdoors.) If they don't enjoy this book, you may officially give up on them.
