In Watermelon Sugar is a novella written by Richard Brautigan and published in 1968. It is a tale of a commune organized around a central gathering house which is named "iDEATH". In this environment, many things are made of watermelon sugar (though the inhabitants also use pine wood and stone for building material and fuel is made from trout oil). The landscape of the novel is always changing. Each day has a different colored sun which creates different colored watermelons, and the central building also changes frequently.
