Night's Dominion (Night's Dominion Vol. 3 #1)

As poison slowly claims the Furie, Emerane attempts the unthinkable. With the help of the Magus's necromancy, she infiltrates the dominion of death itself. If all goes well, Emerane may be able to rescue the Furie's soul from the shores of oblivion. But if she fails, she will be claimed by Uhlume, the god of death.
