This book crossed my radar a couple of years ago, since I'm interested in nature and hiking memoirs, but I'll confess that I decided not to read it due to numerous negative reviews that criticized the author for being judgmental, preachy or otherwise obnoxious. Then when I got notice it was on sale for kindle for $1.99 (I think) a few weeks ago, I decided it couldn't possibly be so bad that I would regret buying it for that price...and I ended up really enjoying this book.
This book is the author's account of the time, fresh out of college at age 21, she walked the entire Appalachian Trail, from Georgia to Maine. While the writing could be a bit more polished (the kindle edition has multiple editing problems, for example), I would like to point out that she (unlike certain better edited authors *cough* Bill Bryson *cough*) actually walked the whole damn trail, and I will give her credit for that alone, because...damn. That's a really long walk.
On top of admiring her achievement, I also enjoyed the book quite a lot. The author's two greatest strengths are her flair for description and her honesty. As for the description--I've never walked the AT and I currently live in an entirely different ecosystem (a.k.a. the remains of the Tallgrass Prairie of central Illinois), and yet, reading Davis's description, I could picture each landscape she traveled through--the "green tunnel" of most of the trail, the barren rock fields of Pennsylvania, the mosquito filled bogs of New England, etc. This meets my primary requirement of reading travel/nature writing: to allow me to picture places I have never been.
She also is adept at detailing her internal landscapes along the way--including her impressions of and reactions to other people--and this is where things might get a bit more problematic. Jennifer Pharr Davis is no saint. She judges some people based on superficial impressions, does not always act in the most mature manner, and has a tendency to whine (whilst simultaneously believing herself to be chosen for some greater purpose). If this sort of thing bothers you in a narrator, then you may not enjoy the book. But it didn't really bother me (even when I could see that she was being petty), because...it's honest. She was only 21, undergoing an extreme journey for her first time, and dealing with some truly challenging moments along the way: under the circumstances, I think it's acceptable she wasn't always perfect. The book felt honest. For me, that's the most important thing in a memoir.
Long story short: if you like hiking memoirs, I would recommend giving this book a try.
