Emily Monosson has brought together thirty-four women scientists from overlapping generations and several fields of research to share their experiences. The authors of the candid essays written for this groundbreaking volume reveal a range of career choices: the authors work part-time and full-time; they opt out and then opt back in; they become entrepreneurs and job share; they teach high school and have achieved tenure. Their stories not only show the many ways in which women can successfully combine motherhood and a career in science but also address and redefine what it means to be a successful scientist.
