Julia Hernandez has vanished without a trace...almost. Actually, she has slipped out of the world she knew and into the Simulacrum: a place between the cracks of human existence from which history is both guided and thwarted by the conflict between a species of anarchist wasp and a collective of hyper-intelligent spiders. Told ultimately from the point of view of another species, Sensation plays with the elements of the Simulacrum already in play: media reports, business-speak, blog entries, text messages, psychological evaluation forms and more.
