Dynasty Of Ghosts — P.L. Nunn

Illya has always been different - fey, quiet, and cursed with the ability to see the lingering spirits of the dead. A younger son of a younger son from a backwater mountain province, he is a nobody in the king's army until he comes to the notice of the Prince Knight himself, the spoiled, stubborn heir to the kingdom of Aldania. Caught up in a war that has raged for generations between Aldania and a neighboring kingdom, captured and imprisoned by a mad king, Illya and Prince Ashe discover a history of lies, betrayal and assassination, and the ghostly truth beneath it all. Opposites in every way, they forge a common bond that pain, war and betrayal will test to the very limit of their strength. To end a dynasty of madness and suffering, Illya must embrace the ability he has always hated, and look to the dead for answers.
