Waveform: Twenty-First-Century Essays by Women celebrates the role of women essayists in contemporary literature. Historically, women have been instrumental in moving the essay to center stage, and Waveform continues this rich tradition, further expanding the dynamic genre’s boundaries and testing its edges. With thirty essays by thirty distinguished and diverse women writers, this carefully constructed anthology incorporates works ranging from the traditional to the experimental. Waveform champions the diversity of women’s approaches to the structure of the essay—today a site of invention and innovation, with experiments in collage, fragments, segmentation, braids, triptychs, and diptychs. Focused on these explorations of form, Waveform is not wed to a fixed theme or even to women’s experiences per se. It is not driven by subject matter but highlights the writers’ interaction with all manner of subject and circumstance through style, voice, tone, and structure. This anthology presents some of the women who are shaping the essay today, mapping an ever-changing landscape. It is designed to place essays recently written by women such as Roxane Gay, Cheryl Strayed, Margo Jefferson, Jaquira Diaz, and Eula Biss into the hands of those who have been waiting patiently for something they could equally claim as their own.
