Black Library: The Relentless Dead (PB)

Oleris III is a dead planet full of tombs and catacombs, and it is on this still world that Colonel Graven and the 401st Krieg Regiment are hunting for a missing inquisitor. Deep beneath the surface, in labyrinthine ossuary tunnels, the dead are stirring, and Graven must battle the spectres of a tragedy of his own making while forging forward.
