In "Chocky," pioneering science-fiction master John Wyndham confronts an enigma as strange as anything found in his classic works "The Day of the Triffids" or "The Chrysalids" the mind of a child. It s not terribly unusual for a boy to have an imaginary friend, but Matthew s parents have to agree that his nicknamed Chocky is anything but ordinary. Why, Chocky demands to know, are there twenty-four hours in a day? Why are there two sexes? Why can t Matthew solve his math homework using a logical system like binary code? When the questions Chocky asks become too advanced and, frankly, too odd for teachers to answer, Matthew s parents start to wonder if Chocky might be something far stranger than a figment of their son s imagination. "Chocky," the last novel Wyndham published during his life, is a playful investigation of what being human is all about, delving into such matters as child-rearing, marriage, learning, artistic inspiration and ending with a surprising and impassioned plea for better human stewardship of the earth."
