Damian

5 star if you read it before your late 20s :)
Which I did, can't remember exactly when but it should be sometime in my teens.
I didn't remember anything about it other than having a significant influence on me
Hence re-reading (actually listening this time) was such an interesting experience. As I came across themes that resonated with me deeply, I wondered if their original source was this book.

I'm not sure if Demian will be meaningful if you are not a “seeker”. If you do, regardless if your age, go ahead and read.
