This had so much promise. Wilderness! Adventure! History! But alas. I'm not a fan of first person present tense - especially in fiction - and then, inexplicably, multiple third-person POVs in every other chapter. So, I read my customary fifty pages and then had to give it up. Switching tenses and POVs is just too jarring; it totally breaks up the flow of the story and I have no idea why authors feel that is a good way to write. Stick to one tense, please. Preferably third person for fiction, first person for memoirs, and past tense for both.
It seems to have gotten decent reviews, though. So the fact that I didn't like it could just be me and my fussy stylistic preferences.
