Synopsis

Once, they were the galaxy’s most fearsome mercenaries… A lot has changed since then. Still, a friend is a friend. So, when one of their old crewmates dies under mysterious circumstances, the infamous Billy Firebrand calls the old crew back together for one last mission. With a busted ship, a lifetime’s worth of demons, and a galactic war on the line, they’ll face odds they probably couldn’t have beaten in their prime. These days… they don’t stand a chance. Ride with Billy, Shotgun, Stick, El, and Mouth as the galaxy’s worst mercenaries face impossible odds, hidden enemies, and… hybrid flying squirrel baboons? Fans of The Worst Ship in the Fleet and Rogue Agent will love this new series full of swashbuckling adventure, witty banter, and plenty of sci-fi fun. Tag along with this crew of has-beens as they redefine what it means to be heroes (and not always in a good way). Set in the fan-favorite universe of Dumb Luck and Dead Heroes , you don't need to have read that series to fully enjoy this action-packed full-length novel.
