“With a transatlantic approach that yields fascinating results, Layne Craig’s When Sex Changed adds nuance, new insight, and fresh ideas to previous historical and literary studies of the birth control movement.”- Beth Widmaier Capo (author of Textual Contraception: Birth Control and Modern American Fiction) "In When Sex Changed, Craig breaks new ground by establishing the transnational nature of the 'political ascendance and gradual institutionalization of birth control as a family planning model' with a well-researched history of birth control politics. She succeeds in bringing to light new meanings buried in texts well combed-over by literary scholars."(Modernism/Modernity)
