Ben signed up to be a highly paid pharmaceutical consultant, not an industrial spy in Miami.
Rebecca signed up to be a world health physician, not a hostage in the Brazilian Amazon.

Series author Dirk Wyle has created a new kind of mystery-thriller — powered by medical science, business and anthropology, and driven by the professional challenges of a two-career couple. In a stunning climax, Ben and Rebecca are reunited to discover astonishing truths — and to fight for their lives.
