Science fiction/nature/entrancing books

Im looking for some can’t put down books that have a deeper philosophical meaning and kind of suck you into another world.

For instance, I recently LOVED Piranesi, I love most Jeff Vandermeer books(Annihilation, Borne, city of saints and madmen), also looking for something that could steer towards spirituality such as The Alchemist…..

Thank you in advance! About to go into surgery recovery and won’t have my legs for a couple weeks. In need of some good ones!
