I am looking for a book for a solo trip.

Next Friday I start a two-week vacation, which I haven't had in 5 years. I plan to spend it without all electronics and in the wild. I want this time to be exclusively for me, where I can be alone with myself and dialogue with myself about what I am looking for and what I need to change in my life.

Could you recommend any books that I could take with me and that you think could help me in some way?
