This is more or less an expanded version of Path of the Fury, with what can be considered a prequel to the original added at the start of the book. This fills out elements hinted at in Path of the Fury.
While Path of the Fury is a fun little book, this expanded version is horrible. Path of the Fury was written early in Weber’s career, when he was still writing hard hitting, fast moving, action packed military science fiction. Then he slowed down and became a word pooper. The new section is ponderous and verbose ad nauseam like his later works. I really tried but I could not get through the new material.
