The gates of hell

Elias Holm is the Commandant of the Marine Corps, a hero who has fought a hundred battles all across human-occupied space. He's led massive armies in the greatest battles ever fought in space. But once he was only a captain, thrust into command when a crucial operation went horribly awry.

The Second Frontier War had raged for a decade. Throughout human-occupied space, worlds were in ruins, the battlegrounds of the Superpowers' eternal struggle. The climactic battle would be fought on the planet Persis, and Holm would have to fight not only the Caliphate's elite Janissary soldiers, but also treachery and betrayal from his own government.
