Riders of the Dead — Dan Abnett

TWO EMPIRE SOLDIERS get their first taste of battle when they join the campaign to repel the savage Northern Tribes. As the winter draws in, the last major battle sees their destinies thrown into turmoil as circumstances tear them apart and throw them onto opposite sides. Such is the mutating power in this dark and terrible land that the strongest of friends can soon become the bitterest of enemies and as they race towards a final cataclysmic showdown, the fate of their souls will be sealed forever.

A sweeping epic of total war and its devastating consequences from the author of the stunning Gaunt's Ghosts series and the Eisenhorn trilogy
