Sight Lines is the tenth poetry collection by Arthur Sze. It was published by Copper Canyon Press in April 9, 2019.
The collection won the 2019 National Book Award for Poetry (USA). Judges of the prize praised Sze's "quiet mastery which generates beautiful, sensuous, inventive, and emotionally rich poems."
Publishers Weekly called it "finely crafted and philosophical".
In her review for The New York Times, Tess Taylor wrote, "This is a poetry of assemblage, where violence and beauty combine and hang on Sze's particular gift for the leaping non sequitur."
Florian Gargaillo of the Colorado Review praised Sze's philosophy represented through strikethroughs, writing, "It is this degree of self-questioning, this wariness of authority in himself and others, that makes Sze such a valuable poet for this moment."
