1915: As Europe grinds through its second year of the Great War, young Oscar “Oz” Vogel enlists in the Imperial German Army, eager for adventure. But nothing can prepare him for the horrors of the Western Front. Through Verdun, the Somme and the blood-soaked fields of Flanders, Oz endures relentless artillery, disease and the deaths of his comrades. Yet the true nightmare begins after he witnesses a horrific war crime…because that’s when he starts seeing them. The Höllenhund, black dogs of hell, hunting the wicked. With U.S. Marines closing in on Belleau Wood, Oz fears not the enemy, but the hounds stalking him. Are they the fevered visions of a soldier pushed to his limits, or demons come to drag him to hell? And even if he can survive the war, how can he hope to escape the Devil’s wrath
