Looking for my next read

I have like 20% left from Hermann Hesse – Narcissus and Goldmund and I want a bit of shorter book for next. I've already read Demian, Siddharta, The Alchemist just to name similar books.

The list AI came up with is the following:

• Steppenwolf — Hesse (continues Demian's themes most directly)
• Journey to the East — Hesse
• Zorba the Greek — Kazantzakis
• The Old Man and the Sea — Hemingway
• The Zahir — Coelho

I love the spiritual part of the books so I use these as a wind down before sleep or as an audiobook for commuting/house chores.

Anybody has a good list or comment on this list?
