This remarkable band of warriors fights an elusive enemy, traveling through dangerous portals of time and space, where reality and un-reality collide in stunning, deadly purpose…Light of the damned…The diamond mines of the Congo are ground zero for a calculated new power grab by an ancient Mesopotamian god. Darkened and depraved, Nergal intends to harness the power of light to lock humanity in the blackness of eternal damnation. But Nergal's ability to blind his opponents is only the beginning. The Cerberus rebels will have to find the human who's pulling Nergal's strings…which means venturing into the gaping mouth of hell itself.
