This book went to the top of my reading list, as it satisfied both my spot in the Walking Dead Board Game (my thread here, Read a book with "wild" in the title) and a task in the I-Spy Challenge (my thread here, title overlaps with Call of the WILD). I was disappointed. 
 This book has some problems, many of which are summarized here. Though some of those problems are with the truth/consistency of the work, even if I view it as fiction, I didn't enjoy the story much. I was hoping for more about the Pacific Crest Trail and its community, and how she learned more about backpacking and wilderness safety; it turned out to be more a story about loss and redemption (sad and full of grisly details) with the PCT as its backdrop. The gushing admiration from all characters she met (many of which she described uncharitably) got old pretty fast. 
 The Book Riot 2016 Read Harder challenge has as Task 18 to "Read a book that was adapted into a movie, then watch the movie and debate which is better" but I don't think I'll bother with this one.
