The Trade Mission by Andrew Pyper

Imagine your job is to translate for the two twenty-something internet millionaires on business in South America. Imagine you are required to accompany them on a boat trip ip a tributary of the Amazon. Imagine that late one night some unknown assailants steal onto the boat and kill the crew. Imagine that you and your employers are kidnapped at gunpoint. Would you risk your life for theirs?

Crossman is faced with just this dilemma. Thrown into a pit for a prison and with the threat of torture to keep them there, rich kids Wallace and Bates, their two colleagues and Crossman are engaged in a battle for survival. But when the increasingly unstable Wallace engineers a violent escape, the rules of the game are forever altered and their own personalities emerge as a threat potentially more dangerous than the jungle that surrounds them and the sadistic gunmen who relentlessly pursue them . . .
