PI Harper Blaine sees a strange shift in clientele in Richardson's dizzy urban fantasy debut. After being dead for two minutes as a result of a clobbering by an angry perp, Harper discovers icky side effects complicate her Seattle life in unexpected ways-she sees ghosts and attracts otherworldly business as she pops in and out of a shadowy overlapping world. Harper seeks the assistance of Ben Danziger, self-proclaimed "ghost guy" and linguistics professor, and his wife, Mara, a witty Irish witch. They educate Harper on the Grey, "a place between our world and the next." Harper tries to maintain a normal life, dating a sexy antiques expert while battling wits with Seattle's vampire king, but being a Greywalker means she can only "pass for human."
