DemonTech series is best described as one part fantasy, one part military, one part sci-fi, and one part a hellaciously good read! In David Sherman's fascinating novels, humans and demons co-exist in a world where the demons are tamed and their abilities used as a type of technology.

The diabolic armies appear invincible–
but they haven’t met the Marines.

The Dark Prince’s power to summon demons has made his forces second to none, and ensured his place as one of the invasion’s leaders. Not content to merely seize his father’s throne, the renegade royal dreams of world conquest–and with his army and his black arts, there is little to stop him.

So unexpected, so well planned is the invasion of the free port New Bally that out of hundreds in the city, only two escape capture. Haft and Spinner will need all their courage and cunning to retrieve their weapons from their enemy-held ship, cross the open meadows surrounding the city walls, and escape into the forest beyond–where they hope to regroup and drive back the invaders. Luckily, Haft and Spinner are no ordinary men. They are Marines . . .


From the Paperback edition.

Ruthless and seemingly indestructible,
the dark army didn’t count on the few, the proud, the Marines.

The Dark Prince’s vast armies have destroyed nation after nation with the aid of powerful demon magic. Their total victory would be swift and certain except for two things: Haft and Spinner, a pair of soldiers trained in the art of warfare through the teachings of a magically transported Marine Gunnery Sergeant.

The Dark Prince’s orders are swift and simple: find them. Haft and Spinner, along with scores of soldiers and refugees, are determined to form an army and defeat the invaders. Outnumbered and outgunned, they must uncover and kill the enemy before the enemy kills them. Haft and Spinner have already accomplished great feats. But to achieve the impossible will require a few strokes of genius and a few good men. Fortunately, these Marines have both. . . .

Only a miracle can save them now.
Luckily, they have one: the Marines.

Like an invincible tidal wave of evil, the Dark Prince’s conquering armies roar across the land, leaving death and destruction in their wake. So far Marines Haft and Spinner have managed to stay one step ahead of the invaders, picking up hundreds of refugees and soldiers as they struggle to reach their salvation at the edge of the sea. Against all odds, they’ve even managed to inflict some damage on the vastly superior forces.

Yet for every enemy soldier killed, ten more appear in his place, and the Dark Prince’s demon magic ensures their weapons are brutally effective. The outlook is not promising for the ragged band of rebels, pursued by bloodthirsty troops, hounded by bandits, and forced across a desert where death awaits all trespassers. As the noose tightens and the Dark Prince prepares the final coup de grace, it may look like Haft and Spinner and their embattled crew are finished. But these Marines have only just begun to fight.
