Joanne Walker, a likable young Seattle beat cop, continues to learn the ropes of her even more dangerous job as a shaman in Murphy's spirited second urban fantasy (after 2005's Urban Shaman
). After a fencing lesson at the university, Joanne stumbles on the body of Cassandra Tucker, a 20-year-old junior, in the showers. The autopsy report states that Cassandra's death was due to a heart condition, but Joanne suspects otherwise. In her role as shaman, Joanne investigates "the Dead Zone," a place between life and death, while her earthside sleuthing leads to a coven that in recognition of her special abilities invites her to take Cassandra's place in opening a passage between worlds for Virissong, an ancient Native American spirit who's expected to end a local heat wave and global warming. Unfortunately, if not surprisingly, Joanne discovers after several nightmarish and somewhat bloated magical misadventures that Virissong is one nasty lying serpent. (May)
