I now travel a lot slower than I used to when I just started with solo traveling couple of years ago, meaning I spend lot of time in coffee shops or laying in parks instead of exploring. So someone gave me a tip to get a book that takes place where I am traveling, and I did so twice: Scotish Myths + Treasure Island (Scotish author counts) while I was in Scotland, and now read Serenity when I was visiting Athens.
It really hits different to read about the place I was visiting, looking around and picturing the scenes from the book taking place at this and that landscape. And also now that I am back home I keep reading it and it brings good memories back.
