Affliction

His parents were heroes, and now he may get his chance to be one. Whether he's ready or not. When Kyo's godfather is infected by the corruption-a spreading affliction that turns people into murderous shadow monsters, he goes to the only mages who can help. But the duo are not the kindly healers they appear. Kyo stumbles upon the victims of their manipulation and necromancy magics, and during the confrontation, the pair vanish with his godfather as a hostage. Desperate to reclaim his family, Kyo gives chase, but his first encounter teaches him he won't defeat them alone. With the help of an anxiety-ridden cleric, a runaway princess, a fatherly stowaway, and a ten-year-old with the power to summon gods, he sets out to stop the mages before they turn the entire world into living dead and ravenous shades.
