Through heartbreaking, often comic, genre-non-conforming pieces spanning the past 10 years, Rachel Zucker trains her relentless attention on marriage, motherhood, grief, the need to speak, depression, sex, and many other topics. Part poetry, part memoir, part lyric essay-and not limited by any of these categories-SoundMachine is a book written out of the persistent feeling that the human voice is both a meaningless sound and the only way we know we exist.
