It is nice to see the series continue. Seems simplistic with the small military squad based world. All firefight. The 1st LT leads the squad of about 7, and operates as de-facto #2 for the Space Carrier (she is Infantry and Space Wing commander). Everybody else (in the squad) is a 2nd LT, a fighter pilot/infantry fighter. Seems Astrid is the only one with a college education. Everyone appears to be in their early 20s, though the maturity seems to be about high school level. While the "combat" scenes are graphic, the narrow focus seems limiting and not really realistic. There are a lot of chapters, each linking to a key phrase and an advance of the story line.
