Aurora, I sort of agree with golfer – SY Agnon was a great author, but even though he did use many torah sources in his works of fiction (for which he won a Nobel prize), He was not writing as an explainer or strengthener or teacher of Jewish practice or philosophy, and did not purport to be an authority on Jewish customs.
I also have a lot of admiration for your journey, and I do think you should explore what particular approach to Torah Judaism works for you. Agnon might be an interesting sidebar or illustration of Jewish life and tradition, but he was primarily a writer of fiction.
