Sword of the Gods

Sword of the Gods is the second novel overall, and the first Forgotten Realms novel out of two, in the worlds-spanning Abyssal Plague series.

"What you don't know will kill you...

Demascus awakens surrounded by corpses, at a shrine littered with traces of demonic rituals, with no memory of his past. But the Firestorm Cabal remembers him—and the demon who leads them seems to have a personal vendetta against him. Dodging knives, uncovering clues left by his past life, and dueling demons, Demascus must figure out who he is, what battles he is fighting, and who is hunting him before one of them catches up with him."
