Query: What went wrong?

This book started so well. A lost scout for the good side gets caught behind enemy lines. He accidentally becomes the wielder of an amazing sword, but doesn't know what it does. He is able to get back to his own forces. His own magicians study and discover some of the features of the sword. The generals decide this will be their secret weapon. The scout becomes their designated assasin. Wonderful! Then something goes wrong. Characters are talked about without any contribution to the storyline. The focus becomes the dull time spent between assasinations. Then the war ends by an act of god with no involvement by the main character! But that's not where the book ends. After a wonderful start that leaves open so many avenues for weaving an intricate tale, the author seems to have given up. Just like a wood chip thrown into a river, the hero is a victim of circumstances even though he has possibly the most powerful weapon on the planet
