Fluke; or, I Know Why the Winged Whale Sings is a novel by American writer Christopher Moore. Published in 2003, it combines elements of absurdist and fantasy fiction, as well as the author's own brand of social commentary and humor. A serious theme in the novel involves environmentalism, particularly that associated with whales; and the author's personal research-experience with marine biologists helped to inform much of the story. An unabridged commercial audio cassette recording of Fluke has been issued with narration by Bill Irwin and whale songs. On July 29, 2004, NBC's Today Show author Nicholas Sparks chose Fluke as the next title to be read by the Today Book Club. Source: Wikipedia (en)
