On the colony planet of Harmony and Reason, the colony’s shareholders are an entitled and elitist upper class, while the rest of the population is poor and indebted. Most of the lower class is made up of “Vats”, vat-grown humans based on genetic material brought from Earth. To make matters worse, insectoid/arachnid aliens have invaded, and the incompetent shareholder military leadership is doing poorly. With the aid of alien technology, the humans “uplift” rats and bats to help fight the war. The bats are flying sappers with Irish accents and strong political views. The rats are nymphomaniac drunks acting as infantry. The action centers on a group of grunts who find themselves stuck behind enemy lines.
Despite the completely absurd premise, or perhaps because of it, this was quite a fun book. It is written with tongue firmly in cheek and humor firmly in the gutter. I enjoyed the misadventures of this one particular group of misfits, replete with constant inter-species sniping and a bitterly resigned attitude towards the idiocy of the brass.
