The most realistic look at war and rulership that can be found in any Forgotten Realms book. If you're looking for lighthearted fare where all the good guys live, look elsewhere.
If you're looking for an excellent story with characters you can care about, look here.
I've read entire stories where an author has failed to do what Greenwood and Denning manage to do in only a few sentences: Make an individual character, even a short lived one, come alive. And that makes their ends all the more tragic. The soldiers dying in the field aren't generic redshirted security officers being beamed down to die like fodder. They're good hearted, often humorous lads, who you hate to see go.
So good. One of the best FR books I've read. A must read.
