Willa Cather and Sylvia Plath are two of the most influential American women writers of the last century, although they could hardly be more different.  In her novel, My Antonia, Cather wrote of harshly beautiful landscape and resilient women adjusting to a new country. Sylvia Plath gave a new voice to the interior lives of women, and inspired many to write and look for a place in literature. Michael Enright speaks with writers and academics about the work and legacy of these two remarkable writers.
