The books are, of course, wonderful (well, what did you expect from a newsgroup
which discusses them :-). Perhaps the more widely discussed on this newsgroup
are the Shannara books, which are as follows:
---Prequel---
First King of Shannara
---First Three---
Sword of Shannara
Elfstones of Shannara
Wishsong of Shannara
---Heritage of Shannara---
Scions of Shannara
Druid of Shannara
Elfqueen of Shannara
Talismans of Shannara
This list orders them in the order in which the events in them happen -
e.g., the events in First King of Shannara happen before the events in Sword of
Shannara. However, First King of Shannara is in fact the most recently written
of the novels. While they are best read in the order as above, First King is a
bit dubious. There are good reasons for reading it both before or after the
other books - it obviously is written to take advantage of the previously
published works, but it also is a good prequel(although this is arguable).
However, the books which are grouped together should be read in that order,
especially the Heritage series, as they form a single story. The second series
he wrote, the Magic Kingdom series is as follows:
Magic Kingdom For Sale..SOLD!
The Black Unicorn
Wizard at Large
The Tangle Box
Witches Brew
These to be read one after meals in the order above until the course is
finished. :-)
The third series he wrote, the Word and the Void series(unofficial name) the
name DelRey is using appears to be "Demon series", and it might be "Trollstown"
although this is unconfired,the series as is as follows:
Running with the Demon
A Knight of the Word
