Long-running military science fiction is a discipline of its own, and the Undying Mercenaries sequence is where B.V. Larson practises it. Instalments arrive, the roster shifts, the war does not end, and listeners who commit to a series shaped this way tend to stay with it for years.
Our catalogue files the books under science fiction and fantasy at once, which is fair enough. The hardware is science fictional, but the appetite being satisfied is the older one for campaigns, comradeship and impossible odds.
