I have a solo 3-night backpacking trip in northern Maine coming up and I'm looking for book recommendations. Ideally somewhat slim for packing, or lighter in weight. Printed book only. Devices staying at home. While I'll be mountain climbing and hiking mostly, I'll have some downtime and always expect a little rain to keep me in the lean-to. I don't really get into the classic rock biographies but I'm open to anything. Thanks!
