Report on Probability A

Report on Probability A is a science fiction novel by British writer Brian Aldiss. The novel was completed in 1962 and published in 1967 in the British magazine New Worlds after first being rejected by publishers in the United Kingdom, France and the United States. Report on Probability A has been described as an antinovel. It is a seminal work in the British New Wave of experimental science fiction that began appearing in New Worlds following the appointment of Michael Moorcock as editor in 1964. A revised and extended version was published by Faber and Faber in 1968 and Doubleday in 1969. New Worlds described it as "perhaps [Aldiss'] most brilliant work to date".
