Drop Marines Books in Order

An alien invasion leaves four thousand civilians stranded behind enemy lines. Jack Keegan and his Drop Marines launch an unlikely rescue mission, only to find that saving them could draw the company into an interstellar war.

The Baow once fought Jack Keegan’s mercenaries; now an admiral wants to hire them for an alien civil war. Expanding forces and richer contracts bring the Drop Marines against enemies who already understand their tactics.

Jack Keegan leads his Drop Marines beyond explored space to salvage an ancient fortress filled with powerful technology. Alien defenses complicate the expedition, and a rival armed salvage crew arrives determined to claim the prize.
