Need a read for a solo camping trip, may or may not be really emotional

I am going to be solo camping around Oregon in a couple weeks after visiting my LDR bf (thus the potential for me being emotional) and want something a bit meaty to read. If I hadn't already read both of these titles I would probably bring East of Eden or the Overstory, but I want something new to engage with. I'm open to any genre but gravitate towards literary fiction, historic fiction, and classics. Ideally I'd like a book that is pretty long as I don't want to finish reading it out in the woods and then be stranded bookless!
