A collection of lyric essays that considers the way subjects, stories, facts, and memories are as interconnected as streams in a watershed, Heidi Czerwiec's Fluid States explores the interlocking issues created by the oilfields of North Dakota; the ephemerality of perfume, canning tomatoes, a fungus that infects and transforms mushrooms; and being the focus of internet hate. Short essays that present delightfully surprising facts with elegant and lyric language, her pieces all share underlying currents that question assumptions about gender, violence, reason, and intuition.
