Cloaked in the web's anonymity, part-Hopi computer hacker Laura Winslow is hiding from her past -- but it has found her in the Arizona desert. The daughter she lost years ago is now an angry young woman serving prison time. But Spider's agreement to help the authorities uncover an identity theft ring in exchange for leniency has led the police to a secret burial ground near Casa Grande Monument -- where mother and child are reunited . . . in terror.

The discarded bones are human, and they may be all that remain of dozens of inexplicably missing women. In this place of death and silence on Native American land, Laura Winslow fears for her daughter, who may be the next to die -- unless together they can expose an insidious evil blooming beneath the blind eyes of the law . . . the terrible beast that is now hunting them both.
