Two WWI enemies must work together to survive on a lost island of dinosaurs and prehistoric tribes in this classic sci-fi fantasy novel. Shipwrecked by a German U-Boat, American soldier Bowen J. Tyler and the beautiful Lys La Rue are the only survivors. They join forces with a British tugboat crew and manage to survive by taking over the German sub. Now, operating an enemy ship, they are unable to find safe harbor. And with a saboteur aboard, they soon go wildly off course. Adrift in Antarctic waters, the half-starved passengers spot what appears to be their salvation: the lost island of Caprona. But once they pass through the island's exterior cliffs, they encounter a host of dangers believed to be long extinct. In a tropical land full of dinosaurs and Neanderthal tribes, double crosses within their own ranks may yet be the worst threat of all. But when Lys goes missing, Bowen will risk his life-and his last chance to escape the island-to find her.
