Marijane Meaker (born May 27, 1927) is an American novelist and short story writer in several genres using different pen names. From 1952 to 1969 she wrote twenty mystery and crime novels as Vin Packer, including Spring Fire which is credited with launching the genre of lesbian pulp fiction (although few of Packer's books address homosexuality or feature gay characters). In 1972 she switched genres and pen names once more to begin writing for young adults, and became quite successful as M.E. Kerr, producing over 20 novels and winning multiple awards including the American Library Association's lifetime award for young-adult literature, the ALA Margaret Edwards Award.
