The result of an ancient attempt to save Earth from a plague of demons slumbers in the Harvard Museum of Comparative Zoology repository. The attempt failed. Demons walk the streets wearing the faces of humans, feeding on the life essences, and sometimes the flesh, of their unknowing prey. Aleksi, a young paleontology graduate student seeking only solitude and study, finds the long-forgotten specimen, and the ancient experiment begins anew. Dreams of dragons plague her sleep, and greedy eyes watch her discovery, lusting for the power she has unwittingly awoken. Can she contain the dragon within her, or will she succumb to the irrepressible temptation to feed?
