The basic story line was good military sci-fi (a battle between god and evil). And there is plenty of non-stop action.
However, the hero characters (good guys) are uniformly so one dimensional it was impossible to identify with or feel a connection with any of them.
Similarly, all we’re really told about the enemy (bad guys) is that they are little more than a mob of soldiers attacking a planet. No background or context is provided as to who the enemy’s leaders are, the evil reasons that motivated the leaders to order the attack (the good guys speculate on this but provide no clear or compelling reasons), etc.
So, what the book describes is a conflict between an attacking force and a defending force without a clear description of why the conflict is occurring. For these reasons, i found it difficult to engage with the story,
