Judith Sheffield needs to escape the dangers of the city where she teaches. When a position suddenly opens up in her home town of Borrego, New Mexico, she takes it. Borrego is a small, decaying town that depends on its local oil refinery to serve its residents. Judith expects the town to be its usual boring self but safe. And she remembers many of its residents. She even reconnects with Jed Arnold, who she used to babysit. He's now a teenager, troubled, and neglected by a widower father who is too caught up in problems at the refinery to give his son enough attention. Besides that, Jed feels like an outsider because he is Indian on his mother's side. When Judith tries to reacquaint him with Brown Eagle, his grandfather, Jed initially dismisses the man as being crazy.
Judith can deal with the normal problems of her work and her life. But something extraordinary and sinister is happening in Borrego. An outside company, Unachem, has come in to take over the failing oil refinery, promising to update and expand its operation and bring prosperity. People are dying, and her students are turning into compliant robots. The people she most cares about are being affected, which includes Jed, his father, and the woman who took her in when she returned from the city. Can the company save the town, or is it part of the problem?
Tension mounts as different people act on their suspicions. As the danger grows, the tale gets downright scary, to where I peeked at the final pages of this chiller to see if my favorite characters would survive.
After an explosive climax, four heroes are left standing. The end is abrupt but not disturbingly so. Rather, even though the story stands on its own, enough issues remain to inhabit a sequel.
