From acclaimed author Sean Ferrell comes a gripping historical horror novel set during the devastation of World War I, where the terrors of the battlefield reveal something far worse than enemy fire across the dark, frozen trenches.

December 1916, The Somme. Jack Friday has spent months here trapped in the inhumane environment of the trenches, surrounded by freezing temperatures, omnipresent mud and death, and the relentless thunder of artillery. Haunted by shell shock and burdened by the terrible secrets he cannot escape, Jack struggles to hold on to the person he once was. For every day is a fight to survive...and every night brings memories he cannot outrun.

But Jack also hears the unsettling rumors spreading through the ranks...hushed, frightened talk of soldiers' mutilated remains being discovered. Convinced that something far more dangerous than a German sniper bullet is moving through the battlefield, Jack finds himself drawn into an obsessive search for answers as he fights the darkness growing within himself. Beyond the trenches, somewhere within the shattered wasteland of shell craters, corpses, and ruin, there is a presence seemingly untouched by the rules of war?one that has been watching, waiting, and feeding on the chaos around it...
