I echo the suggestion above to read Tolkien's Lord of the Rings trilogy - and I recommend reading "The Hobbit" first. These have become true classics of fantasy, and they will not disappoint you. Definitely best read in English, as the prose and phrasing of J.R.R. Tolkien carries the flavor of the medieval literature which was the focus of his outstanding scholarship.
Another book I strongly recommend is one of the most honored in science fiction: Robert A. Heinlein's book "Stranger in a Strange Land". It has a couple of slow spots, but it was an extremely influential book in the 60's when it was first published, and it's a fantastic story.
I am really not a fan of fantasy. So that will not be a priority for me.
Thanks for the suggestion though.
I looked up Stranger in a Strange Land.
It's on my wishlist on Amazon.
That seems like my kind of novel.
If I understand correctly from reviews... there is a bit of theological aspect to it? Or religious (and philosophical and social).
Great suggestion.
