Lo, these many years ago I read this. After seeing the TV series I decided to revisit the books. I remember borrowing them from the Libraries at the time but I only read so far before stopping, I think I just stopped caring and now that I'm revisiting I'm finding that I don't really care what happens to the characters outside of seeing where the plot is going to lead them. It is interesting to see a world that 's more SF than fantasy as it's a post apocalypse story where Elves, Dwarves, Orcs and all of that are as a result of a catacalysm and it's quite complicated.
Shea Olmford is a half-elf and Allanon takes him from his familiar world to help save the world from the Warlord King as he's the last heir of Shannara and the only rightful bearer of the Sword of Shannara.
It has a few lazy "all x do y" moments but otherwise quite readable.
