I really enjoyed following this journey on audiobook, and I think it especially works because of its combination of travel memoir and psychological journey. It's one of the most genuine looks at grief I've ever read (though I shy away from sad books generally, so there are probably other great ones out there). Her honesty in all things is a strength, even if its sometimes shocking. 
 Her hike itself gets a little monotonous (the sore feet, the rapture of food), but without it you wouldn't get a true understanding of the monotony of such a hike. It didn't make me want to hike the PCT, but I do want to return to the Pacific Northwest sooner now.
