Hi!  Have you heard of the Chronicles of Thomas Covenant?
Yes, Love it. It's series of ten high fantasy novels written by American author Stephen R. Donaldson.
Interesting!  I love the Lord of the Rings books.  Is it comparable?
Not really. It's about The Illearth War", and covers an episode from the doomed mission to contact the Giants.
Interesting.  I am very curious about the books now.  Are the books quite long?
Some longer then others. It took me 2 years to read all of them.  The first  It describes Korik's selection of the mission's Bloodguard, then narrates the mission's passage through Grimmerdhore forest.
I will look into these books.  Has the author written any non-seried books?
You know I'm not sure if American author American author Stephen R. Donaldson wrote anything else. He must have.
