Finally saw this in the bookstore the other day. I've been wanting to dig back into Terry Brooks' Shannara stuff that I enjoyed in high school and thought that this prequel series would be a good place to start without having to immediately re-visit the books I've already read.
Brooks isn't a brilliant writer and his first book The Sword of Shannara is a blatant Tolkien rip-off, but as he went along he got more imaginative and the world of Shannara is a fun and engrossing place to visit. One of the cool aspects of it is that even though it's a fantasy world, it's actually set in the far future of Earth. Armageddon's Children starts the series that bridges our reality with the Shannara world.
