The lost city of Heracleon

"Called to adventure, young boys Lou and Shiro find themselves on an inter-dimensional submarine captained by an off-the-hinges old man. They soon discover Lou's missing father might still be alive as they are transformed into fully grown warriors headed straight for the battlegrounds of Ancient Egypt, the Lost City, and 1914 Sarajevo. As the gods tinkering with fate become reckless and apathetic, the boys become part of a legion hell-bent on restoring balance to humanity"--Back cover.
