Overview
Kat Richardson’s nine-book urban fantasy series (2006 to 2014) follows Harper Blaine, a Seattle private investigator who becomes a Greywalker after being clinically dead for two minutes: she can now cross into the Grey, the paranormal realm that overlaps the everyday world, where ghosts, vampires and stranger things are real. Her cases mix detective work with the supernatural, and the later books follow a longer arc about her own past and her powers. The ninth novel, Revenant, was described by the author as the last, at least for a while.
