Swept from the World War II Pacific into an alternate world, Lietenant Commander Matthew Patrick Reddy and the crew of the USS "Walker" have allied with the peaceful Lemurians in their struggle against the warlike, reptilian Grik. But the greatest threat is yet to come. For the massive Japanese battleship that "Walker" was fleeing back in the Pacific also came through the rift, and it's in the hands of the Grik.

Pressed into service when World War II breaks out in the Pacific, the US "Walker"?a Great War-era destroyer?finds itself retreating from pursuing Japanese battleships. Its captain, Lieutenant Commander Matthew Patrick Reddy, desperately leads the Walker into a squall, hoping it will give them cover?only to emerge into an alternate world. A world where two species have evolved: the cat-like Lemurians and the reptilian Griks?and they are at war.
With its power and weaponry, the "Walker"'s very existence could alter the balance of power. And for Reddy and his crew, who have the means to turn a primitive war into a genocidal Armageddon, one thing becomes clear. They must determine whose side they?re on. Because whichever species they choose is the winner.

In the Pacific, as "USS Walker "is repaired and updated after a previous battle and Matt Reddy is healing from his wounds, planning begins for a bold raid on the very heart of the Grik Empire.
But time is running out for the Alliance army in Indiaa, and the Allied forces in the west must gather in an unprecedented land, air, and sea campaign to destroy the mighty Grik battle fleet and break through to their relief. All other plans go on hold when the attempt proves more difficult--and more heartbreakingly costly--than anyone imagined.
Meanwhile, the struggle continues on other fronts near and far: in the jungles of Borno in distant southern Africa and in the Americas, where the Allies are finally learning the terrible truth about the twisted Dominion.
The Alliance is on the offensive everywhere, but their enemies have a few surprises, including new weaponry and new tactics...and a stunning geographic advantage that Reddy never suspected.
Until now.
