The Miscreant (An Assassin's Blade)

There is a realm the living were never supposed to visit and the dead were never supposed to leave. The rules have changed. Astul, an infamous assassin with a woeful reputation, finds his brother's corpse curiously absent from its tomb. This amid accusations that grave robbers are terrorizing the world of Mizridahl. But Astul soon discovers the cadavers aren't being robbed. They're being gathered. Harvested. A dreadful enigma creeps into Mizridahl, with the might of an army that was never supposed to see the living realm again. Astul lost nearly everything dear to him when conjurers swept across his world four months ago. Now he stands to lose the rest. Conjurers were the beginning. This is the end.
