The Hitchhiker's Guide to the Galaxy
by Douglas Adams
✅"A towel, it says, is about the most massively useful thing an interstellar hitchhiker can have". This is just one of The Hitchhiker's Guide to the Galaxy's (an electronic book not too dissimilar to a modern day tablet) handy tips for any would be intergalactic traveller planning to trek their way across the universe.
