The pages flew by.
I enjoy military sci-fi novels.
This one had all the factors.
First and foremost: character developments.
Another factor in this trilogy I enjoyed tremendously, was an academy-like setting.
In this case there was a basic training part; plus a special forces one, set on its own Planet: Hades.
Throw in a fungus type of plague-like-intelligence; enemies from various parts of the galaxy; all
awaiting the graduates, and you have an entertaining read.
