I love Hermann Hesse.
Peter Camenzind reminded me of a 1900's version of On the Road
set in Switzerland. Prone to melancholy and drunkenness, Camenzind's wanderlust and love of nature might be better compared to Kerouac's Big Sur. Both books describe characters that you want to succeed, but end up drunk with their hearts broken. They also show an intelligence and self-awareness of the reasons of their failures.
Which makes sense why Hermann Hesse and Jack Kerouac are two of my favorite authors.
