Doris Lessing’s many books include poetry, memoirs, reportage, plays, essays, and reviews. She is best known, however, for her novels, particularly The Golden Notebook (1962), and the five-volume Children of Violence series, which includes Martha Quest (1952), A Proper Marriage (1954), A Ripple from the Storm (1958), Landlocked (1965), and The Four-Gated City (1969). She explored the genre she terms “space fiction” in the volumes Shikasta (1979), The Marriages Between Zones Three, Four, and Five (1980), The Sirian Experiments (1981), The Making of the Representative for Planet 8 (1982), and Documents Relating to the Sentimental Agents in the Volyen Empire (1983), as well as “inner space fiction” in novels such as Briefing for a Descent into Hell (1971) and The Memoirs of a Survivor (1974). In the mid-1980’s, she returned to more realistic fiction, publishing, among others, two novels under the pseudonym Jane Somers. In the 1990’s Lessing published the novels Playing the Game (1995), Love, Again (1996), and Mara and Dann (1999), as well as the dramatic Play with a Tiger, and Other Plays (pb. 1996) and the autobiographical Walking in the Shade (1997).
