Undying Mercenaries: Audiobooks in Order

Mark Boyett narrates Hell World, and a single steady voice matters enormously in a series this long; listeners who commit to 25 instalments want continuity in their ears as much as on the page. At nearly 13 hours, this is the sort of production built for commutes, long runs and slow Sunday afternoons.Be honest with yourself about where to start, though. Volume 25 is a deep entry point, and my instinct is always to begin a long series at the beginning rather than parachuting into the latest campaign. If you enjoy sprawling speculative adventure with military bones, and you like knowing there are two dozen further volumes waiting, this is precisely the kind of back catalogue worth budgeting for.
