Having beat the Malwa in Persia Belisarius takes the fight to them. The fights here are big and epic, but unlike the last book they are too complex and large scale to be fun tactical exercises. Here it's all about the long-term strategic damage to their logistics. Basically this is World War II invasion of Europe. Which means that Belisarius doesn't get to be everywhere at once. This means that there are a lot of secondary characters who take front stage to be close to the action. I liked the last book better, but this one is still excellent. Nothing deep, just a lot of really entertaining fluff.
As I said in my previous reviews these books are not particularly deep, but they are immensely good fun action novels. They feature evil beings from the future, alternate history, Romans and Indians fighting with gunpowder weapons, unkillable warriors, and a general who's never wrong. These two books are occupied with concluding everything that went before. As such they lack the originality and one man heroics of the first volume and the continual practical tactical stratagems of the second. Everything is a confused mess as Belisarius throws the Malwa into disorder. This makes for less clear reading than the last two volumes, but it makes up for it with its epic scope and the fact that it ties up all the loose ends in a (relatively) satisfying conclusion. As with all the books this one ties everything up a little too nicely, but you can't have everything. Having put up with it for two volumes the in jokes, cliches, and repeated themes are enough to drive a man mad. Hearing someone call Belisarius a genius every few pages gets to the point where you can no longer ignore it. But that's what you get when you have a series of six books covering a basic, but complicated plot. A good book, but not one which you can just pick up on its own. Read the other two first.
