I got two series I want to put up to the council for review.
First,
The Chronicles of Amber by Roger Zelazny. He's a hugo award winning author and I loved this series of books. It's epic (while might not be considered a classic) and has some great writing. It's 10 books long (short books tho, I have the full series in one book I bought for $25 at a store) and I think could be considered for this list.
Second is just a stab in the dark, but I thought I'd ask.
The Sword of Truth series by Terry Goodkind. Some love it, some hate it. I loved the first half of the series and had to make my way through the second half (just like WoT by Robert Jordan).
I'm not sure if either fits your criteria, but I thought I'd offer them to the judgment of the council.
