My favorite is Zorba the Greek by Kazantzakis, you can also never go wrong with classics like East of Eden, Siddartha, anything by Dostoevsky

The Alchemist for me is the book I recommend to people who don’t read much, it’s a great “introduction” novel to philosophical fiction as it’s easy to read and the message is nice, although glaringly obvious.

It’s good, but favorite book is a character tell
