The Return of The Grand Marshal

When the Shadow Swarm descends on Sterling City, salvation comes from the last man anyone expects—a janitor pushing a garbage cart. One secret code, and the deadliest fleet in the galaxy flees. Governor Ava Sterling vows to unmask him, never guessing the trash worker she's hunting is Zane Cole, the legendary Grand Marshal who erased the Swarm's homeworld. Now enemies hide inside the Council itself, and the galaxy's mightiest man must rise again.
