Knighthawk Squadron, the second book in the Star Crusader series, is decent and enjoyable YA-level military sci-fi adventure and makes a substantial improvement in both world-building and character-building over the first book (Hero of the Alliance). The characters gain more depth and nuance and the history of both the characters and their worlds and governments are revealed in ways that make sense and help drive the story forward nicely. More so than the first book, this one makes me really want to listen to the whole series and see where it all goes. Recommended for fans of lighter military sci-fi.
