While extradimensional demons in disguise prowl the high-rise corridors of power, a twisted, ingenious, and all-too-human murderer stalks the back alleys. Only Ghost, the spectral protector of Chicago, can defend the world from their evil advances! But when a painful encounter with a familiar face sends Elisa Cameron on a hunt to uncover the mysteries of her past life, will she ignore her desperate city...and the friends she's pulled into her chaos? This volume collects the adventures of Dark Horse's intangible heroine from Ghost- The White City Butcher #1 - #4.
