The Seventh Sword is an underread and underappreciated trilogy--a lot is going on under the surface of these three books, but the surface is such a readable story that it's accessible to anyone. The plot, as other reviewers have mentioned, is typical fantasy, but there are major, important differences which reveal themselves in this book and The Coming of Wisdom (2nd in the series). Every time I read these books, I'm swept up in the action, but I also see facets and symmetries I hadn't noticed before. This book, more than the first two, delves into the problems of idealism versus necessity, the proper use of power, what a person's identity really is (body, mind, beliefs, values, memories, reactions, desires?), faith and technology, how people grow and develop, and a lot more. The characters are unforgettable--anyone who's read these books will have an instant reaction to names like Katanji, Tomiyano, Thana, Tivanixi, or Jja.
Read these books, and read them again.
