Overheard Voices examines poetic address and in particular apostrophe (the address of absent or inanimate others) in the work of four post-World War II American poets, with a focus on loss, desire, figuration, audience, and subjectivity. By approaching these crucial issues from an unexpected angle—through a study of the seldom-examined lyric "you"—Overheard Voices offers new insight into both contemporary lyric and the lyric genre more generally. The book offers detailed readings of Sylvia Plath, James Merrill, Louise Glück, and Frank Bidart.
