Then, the Coalition invaded, smashed the fleet and conquered the homeworld. The battered Dark Star barely escaped to wander the stars, helping its centurion eke out a living as a bounty hunter. Now, bad luck dogs Centurion Tanner. On Calisto Grandee, officials jail his crew and impound his ship, demanding fees he cannot pay. Rich strangers offer to hire him…maybe because he’s the only one desperate enough to accept their deal. They’ll pay to fix his ship and promise him a weapon to help him free his world. First, he must race to the galactic rim while there’s time and sneak into the most heavily fortified star system in the galaxy. There, they must destroy an extinction level threat before it can spread like a cancer against humanity. Tanner agrees. Now, the fate of the galaxy rests on one man and one ship to do the impossible before the clock strikes zero.
