Suggestions for solo backpacking trip

I will be backpacking through South America for 2 months this summer. This is my first solo trip!

Looking for great books to accompany great moments, make me feel less alone and inspire big changes in life.
It's a big ask, but we all know those books exist!

Both fiction and non-fiction are welcome!
Bonus points if they're set in the countries I'm visiting: Equador, Peru, Bolivia
