The Mosquito Coast — Paul Theroux

In a breathtaking adventure story, the paranoid and brilliant inventor Allie Fox takes his family to live in the Honduran jungle, determined to build a civilization better than the one they've left. Fleeing from an America he sees as mired in materialism and conformity, he hopes to rediscover a purer life. But his utopian experiment takes a dark turn when his obsessions lead the family toward unimaginable danger.
