Captain Matt Reddy and the crew of the USS Walker have been fighting for their lives, ever since their ship was swept from the Pacific to another world and they became embroiled in a deadly conflict between the Lemurians and the vicious Grik.

With his family and allies prisoners of the madman Kurokawa, the mysterious League and evil Dominion plotting schemes of their own, and the Grik trying to build their swarm and concentrate power, Reddy faces danger on all sides.

Desperate to confront Kurokawa, Captain Reddy is rushing repairs to the Walker, but he fears he's subordinating the war effort for personal reasons-again. Still, Kurokawa can't be left alone. Sometimes, just because you want to do something doesn't mean it's wrong . . .
