Kay Boyle shared the first issue of This Quarter with Gertrude Stein and Ernest Hemingway, expressed her struggles with poetry to William Carlos Williams and voiced warm admiration to Katherine Anne Porter, fled WWII France with Max Ernst and Peggy Guggenheim, socialized with the likes of James Joyce, Marcel Duchamp, and Samuel Beckett, and went to jail with Joan Baez. The letters in this first-of-its-kind collection, authorized by Boyle herself, bear witness to a transformative era illuminated by genius and darkened by Nazism and the Red Scare. Yet they also serve as milestones on the journey of a woman who possessed a gift for intense and enduring friendship, a passion for social justice, and an artistic brilliance that earned her inclusion among the celebrated figures in her ever-expanding orbit.
