On the heels of his acclaimed bestselling debut Lost Girls, Andrew Pyper brings his darkly musical language, chilling suspense, and psychological complexity to a story of survival in the Amazon jungle.

On the delirious eve of the new millennium, Marcus Wallace and Jonathon Bates, two twenty-four-year-old overnight dot-com millionaires, are on a trade mission in Brazil. Their product is Hypothesys, a virtual “morality machine” that promises to help people “make the best decisions of their lives.” But when the decision is made to take an ecotour up the Río Negro deep into the Amazon jungle, the Hypothesys team members are forced to make choices for themselves — choices that carry fatal consequences.
In the dead of night, their boat is boarded by paramilitaries who kill the Brazilian crew and kidnap Wallace and Bates, their two older colleagues, and their enigmatic interpreter, Crossman. Blindfolded and thrown into a pit for a prison, they must fight to find the will to survive. But when the increasingly unstable Wallace engineers a violent escape, their own natures emerge as a threat potentially more dangerous than the boundless jungle that surrounds them, or the gunmen who relentlessly pursue them.
A rare combination of literary skill, contemporary insight, and outstanding storytelling, The Trade Mission is an electrifying read that confirms Andrew Pyper’s mastery of psychological suspense.
