Between this world and the next lies a boundary of shadow, whose borders are crossed under strict rules. When love prompts a shadow dweller to linger in the mortal world, the result is chaos, an epidemic of demonic origin, and the birth of an inadvertent savior. Ghost-hunters, near-death researchers, medical and military specialists, secret government agencies, and a private army of defenders against human annihilation contend in a world of dark terror against a seemingly invincible supernatural horde. Against this background, an angst, fear, and guilt-riddled romance holds the key to human survival. This is a dark, desperate, mesmerizing story, told in prose as densely shadowed as its setting, and a heart-pounding thrill to read. This voluntary, independent ARC reviewer says: Go for it!
