Destroyermen 04: Distant Thunders [audiobook EN] [mp3@64]

After the battle in which the men of the destroyer Walker and their Lemurian allies repelled the savage Grik, Lieutenant Commander Matthew Reddy is shocked by the arrival of a strange ship captained by one Commodore Jenks of the New Britain Imperial Navy-an island-nation populated by the descendants of British East Indiamen swept through the rift centuries before.
With the Walker undergoing repairs, Reddy already has a great deal on his hands. For the Grik will return, and Reddy will need all hands on deck to fight them off when they next attack. But Jenks' uncertain loyalties make Reddy question whether he can trust the man.
As tension between the Allies and the Imperials mount, Reddy will come to realize that his suspicions are not misplaced-and that a greater danger than the Grik is closer than he ever suspected...

Destroyermen is an Alternate History series, it centers around the crew of USS Walker, a World War II destroyer who are catapulted to an alternate world after a disastrous Allied defeat at Java. The new world is right out of prehistory: dinosaurs roam the lands, and the oceans are home to swarms of man-eating fish and giant reptiles. They've also gone from one war to another, for here two very different species have just started up a fight for survival again after several thousand years. On the one side are the Lemurians, (or 'Cats, as the Americans call them) lemur-like sea-goers who have lived a rather peaceful existence until now. On the other side are the Grik, savage raptor-like reptiles hell-bent on hunting the 'Cats to extinction.
