Call of the Dead — Ron Ripley

When ghosts stalk the battlefield, death is only the beginning... Retired Marine Shane Ryan has been waging a one-man war against evil for as long as he can remember. But when an old comrade is killed under mysterious circumstances, Shane's investigation leads him to Vakovia, a country teeming with restless spirits and dangerous secrets. In a war-torn city of the dead, Shane crosses paths with Reaper Company, an elite mercenary unit who fight with ghostly partners known as Spectral Assets. But can these supernatural soldiers be trusted? Or are they pawns in a darker conspiracy? Shane soon finds himself caught in a web of lies, betrayal, and supernatural warfare. With both the living and the dead hunting him, he must use all his skills to survive. From haunted ruins to an underground labyrinth, Shane strikes back, bringing the fight to his enemy's doorstep. But this may be one war Shane can't win. Especially if his enemies won't stay buried...
