Query: Fantasy at its very best.

This book is by far one of the great fantasy novels ever written. In some ways I can't explain how good it is, reading this you almost feel like you are reading historical fiction. The worlds and characters are so detailed, real, and in some cases flawed that it makes relating to them an easy task. Can't say enough good things about it, if you have not got into this genre, this is the book to try.
