During the second mission of the A.S.S. Vorpal Blade, the crew is tasked with a long duration journey in order to investigate what happened to a far-flung research outpost with which contact has been lost. Big space battles with the Dreen ensue, as well as an encounter with an ally.
Just as in Vorpal Blade, the tone is light hearted, with a lot of dry humor pervading the text. No plot development is too hyperbolic for the authors, and therein, in my opinion, lies the charm of the series. It is almost a guilty pleasure. While the physics and logic are unassailable, the attitude is pure sass.
The sequel to Into the Looking Glass takes up the story more than ten years later. The US is launching its first starship, based on a nuclear submarine and and alien propulsion system. The novel follows the mission. It is an escalation of encounters from very mild to extremely deadly, with quantum physics sprinkled throughout.
Unlike Into the Looking Glass, which I was somewhat disappointed with, I thoroughly enjoyed Vorpal Blade. It is a fun romp with the right doses of humor and action. The characters are engaging, fun and well-written. You really get a sense of being with them on the starship. Fun!
