The head of US public relations at Kobayashi Motors, the largest automaker in Japan, is Cadence St. James ... that is, until she's forced to take on the dangerous new role of corporate whistleblower. Cadence's twin sister, Cushmeer Kincaid, is a human rights statistician who suffers from a fear of public speaking.

When Kobayashi cars start spontaneously accelerating and the death toll rises, Toshio Nakamura, a company executive, heads due north to Minneapolis, Minnesota and pulls Cushmeer into the treacherous fray.

Can a secret language between twins bring powerful forces to justice for murder, even from beyond the grave?
