You can’t write a big fantasy novel without a map. That’s just how it is. I’ve always wanted a book with a map in it. This is from the Son of Black Sword landing page over at Baen. http://www.baen.com/sonoftheblacksword_draft.asp
The extremely talented Isaac Stewart did the maps for this project. I’ve been a fan of his work since Mistborn.
EDIT: the sample chapters and a free short story are at that link too.
