Books one should read during a travel sabbatical

So I’m planning to finally make a childhood dream come true and go on a 4-month travel sabbatical. I want this to be a period of personal reflection and growth, and I’m looking for books that will help me in that objective.
What are your favourite transformative books, stories that changed your perspective on life? I’m in my early 30s if that helps.

I mostly enjoy fiction and can’t really do self-help. Some books I read recently and loved:
– Tomorrow, Tomorrow and Tomorrow
– Educated
– Martyr!
– Orbital

Other all-time favourites:
– 1984
– Animal Farm
– The Secret History
– The Goldfinch
– My Brilliant Friend series
– Room
– Pachinko
– Sorrow and Bliss

I haven’t read a lot of classics but there are SO many recommendations out there I don’t even know where to begin! So if you read a book that changed your life (and bonus points if it’s something that goes well with a few months on the road), please leave a comment!
