Rebuilding after the ship-shattering climax of 2009's Maelstrom
, Capt. Matt Reddy and the crew of the dimensionally misplaced USS Walker
continue pushing their Bronze Age allies, the Lemurians, through the Industrial Revolution to take the war to the invading reptilian Grik. Somewhat aided by the paddle-wheel steam frigates of New Britain, Reddy liberates conquered cities to the west and then races to the east in a refloated Walker
to re-rescue New British princess Rebecca Anne McDonald. The fun of watching eager aviators take to the air in carved wooden aircraft leavens the nostalgic sense of worlds being left behind and cultures forced by war to undergo unpleasant changes. Anderson raises questions about the morality of chemical warfare, genocide, and summary execution in wartime while holding out the possibility of diplomacy with relentless killers. (June)
