Book Two of the Steven Kinder Series.
Steve is a 'Star Child, ' a human with an alien soul, and he's not the only one because ravenous man-eating aliens just won't leave his city alone, and Steve hurts everywhere. Just as he reaches his physical limit, he encounters predatory Incarns. Humans radiating alien souls just like his, but with auras drenched in sickening black. More ruthless than any monster he's yet encountered, these new adversaries take a vicious interest in Steve, mercilessly consuming any helpless human who crosses their path. Fighting planet hopping aliens was one thing, but as Steve desperately engages dimensional threats from both above and below, he's on the brink of discovering the vilest monster of them all just might be...the beast within humanity itself
