Book excerpt: Enter the Darkness. Kill Everyone. Save the World. When Arthur Curie learns of a chink in the Darkness's armor, he knows it's his chance to turn the tide in a millennia old conflict. There's just one problem. To take that chance, he'll have to risk his entire army, side with a former enemy, and defeat forces of Darkness far greater than he's ever faced before. But you know what they say, no guts, no glory, right?
