So after trying for like 10 years, I finally got my father to read The Life and Death of Superman by Roger Stern. Took him about a week on and off. A few minutes ago when he gave it back to me after finishing, he (a man whose passion for reading has helped me define my own, though his tends towards the fact based and non-fiction non-whimsical realms of writing) told me it was one of the best stories he had read in years and he should have taken my advice sooner.
We spent almost an hour talking superheros and scifi in general. Something he never does.
