Is it similar to the TV series (if you watched it) or did they take creative liberties? I loved the world building there, but the series itself wasn't really for me, especially the love triangle in which two girls sacrifice themselves while the hero goes on adventuring.
The series starts more with the Elfstones of Shannara, rather than Sword. Brooks was involved, I think. They made the TV show more teen oriented and did take liberties with the book. I think they tried to keep the same basic story line. At least in season 1. Not sure about season 2 of the show.
But it has been quite some time since I read Elfstones, so I'm going off memory.
