Can one start the series from Elfstones of Shannara? I find the first book to be a bit of a drag.
Yes, you can. The first three books in the series -
The Sword of Shannara
The Elfstones of Shannara
The Wishsong of Shannara
Are all stand-alone books. They're sequels, but you don't need to read the previous books to understand what's going on. He puts just enough back story in there so that you can keep up.
It's not until
Scions that you get to the "must be read together" section, as each is a saga/trilogy (and in one case, a duology).
I've been a big Shannara fan for about 15 years. I actually started reading them again last year in prep for the
Dark Legacy trilogy, and I'll admit that
Sword kinda felt like required homework while I was reading it. Other than that, I think the
High Druid trilogy is also a low point. Not bad, really, but you can just
feel it doesn't have the same heart as the series before it.
Voyage of the Jerle Shannara is still my favorite trilogy in the series, but
Elfstones is by far my favorite stand alone.
I honestly think the
High Druid series can be skipped, because like the stand-alone novels,
Dark Legacy puts in enough back story from that series to allow you to keep up.
Sword may be able to be skipped, also, but since I never did I'm not sure. Maybe someone has and can offer an opinion?
Keep in mind, too, that the Word/Void books are prequels to the Shannara series. If you want to go in chronological order, read
Word/Void Series - Running With the Demon, A Knight of the Word, Angel Fire East
Genesis Series - Armageddon's Children, Elves of Cintra, The Gypsy Morph
Legends Series - Bearers of the Black Staff, Measure of the Magic
First King
Sword
Elfstones
Wishsong
Heritage Series - Scions, Druid, Elf Queen, Talismans
Voyage Series - Ilse Witch, Antrax, Morgawr
High Druid Series - Jarka Ruus, Tanequil, Straken
Dark Legacy Series - Wards of Faerie, Bloodfire Quest, Witch Wraith
My personal recommends are
Elfstones, First King, Voyage Series, Genesis Series, and the Dark Legacy series.
Well, now that this went way longer than I meant it to...yeah. Hope you enjoy the books!
