The best books I every read are (as far as I remember, far too many books in my shelf
Memory, Sorrow, and Thorn triologie by Tad Williams. A little bit slow in the beginning, but the story has unique depth and speeds up.
Foucault's Pendulum written by Umberto Eco. Nice story about people who takes all the mystic stuff too serious. Not really Fantasie but great!
All books about Midkemia written by Raymond E. Feist. Especially the Riftwar saga.
The Death Gate Cycle by Margaret Weiss and Tracy Hickman is great, too. I think even better then the good Dragonlance Chronicles and Legends.
The Black Magician Trilogy was not the best books ever I read but very nice ones, too. Written by Trudi Canavan.
If want some funny stuff. Terry Prattchet has some good ones. I would say read as first: Mort
All other books are already mentioned before or I don't remember them.
