Ages ago, sorcerers of unmatched power sundered a world into four realms - sky, stone, fire, and water - then vanished. Over time, magicians learned how to work spells only in their own realms, and forgot the others. Now, only the few who have survived the Labyrinth and crossed the Death Gate know of the presence of all four realms - and even they have yet to unravel the mysteries of their severed world...

The Death Gate Cycle is a seven volume series of books written by Margaret Weis and Tracy Hickman. The books soar above and beyond all others in the genre. I... I can't really say very much, I don't know where to start. There'd be so much to cover.
If any of you have read this series, please, post about it and tell everyone how good it is. For those of you who haven't, read it and see that there's so much more to fantasy - to life - than Eragon or Eldest.

I never heard about these books... Are they really cool? because in this moment I'm searching for something to read at least as good as the Inheritance trilogy, and I wouln't like to be desappointed...

they are a very good books
