Second volumes of trilogies are often viewed as filler between the setup in the first volume and the resolution in the third. That's not the case here. Many of the plot threads from Rise and Fall are resolved, but new ones are added. The characters grow and change, and there were several unexpected twists. The battle sequences were exciting and creative. The ending sets up the next book well. This is a solid work of military fantasy from a writer to watch
The stories in Outcasts are fresh, original, and diverse. A nice cure from generic fantasy and sf. Wisseman moves between fantasy, science fiction, and paranormal with ease. His characters are real people. They aren't always in the best of situations, and not all of them are likeable. But you care about what happens to them. Even when they're their own worst enemies. The stories will stick with you after you finish the book. This is a writer to watch.
