Of course, there's a reference to one of the characters thinking about fleeing to Ventria, so you never know if the island of the Ikenas and Highlands aren't northwest of Drenai...
However, that's not the point. This is an excellent book about the nature of heroism and legend that twists and turns throughout history.
Unlike most of his books, Morningstar is narrated in the first person, in this case by one Owen Odell, a bard/magician who meets and befriends a rakish thief named Jarek Mace, and tells us his story.
As others have said, it's a decidedly different manner of writing for Mr. Gemmell; every other of his books that I've read have been third-person, before and since. It's a very good read, and quite fast, too; it's much thinner than his normal books, and read much faster, which is sometimes a good thing.
All in all, I rather enjoyed this novel, and highly recommend it.
