The Expeditionary Force series starts with a familiar premise: aliens invade Earth. But it quickly takes a sharp left turn into humor and high-stakes adventure. When U.S. Army Colonel Joe Bishop inadvertently befriends a snarky, super-advanced AI named Skippy, the fate of the galaxy shifts.

Together with a ragtag crew of humans, they travel the stars in a stolen spaceship, bluffing and fighting their way through a war between massive alien coalitions. The series is celebrated for its mix of tense space battles, creative scientific solutions, and the hilarious banter between Joe and Skippy.
