Having not read his prior work, but being aware of his growing literary stature, I was pleasantly surprised by the accessibility of Diaz’s writing. His lyrical prose expertly conjures a dilapidated but vibrant, thrumming city that persists amidst its deterioration. Evocative descriptions include a river that “doesn’t run but oozes…like molten ore” or vacant warehouses reclaimed by roots that have “clawed their witchy fingers into the plaster…with an invisible slowness…in the gentlest of tantrums.” I loved these descriptions. I was equally drawn to the way he explores the main character’s background through flashbacks that add depth and texture to her character.

The second half of the novel abandons much of what I enjoyed about the first half, however. An abrupt pivot from first- to third-person narration feels gimmicky and doesn’t justify itself by the book’s end. That, paired with plot beats that require heavy exposition of quantum theory, really dragged things down. The more it leaned into this, the more I leaned away. I appreciate the time and effort Diaz put into untangling the book’s thornier quantum entanglements,* but the story is worse for it.

In all, Ply is most effective and affecting when it drills deep into its characters, and much less so when it gets tangled in convoluted quantum mechanics. That said, I really enjoyed Diaz’s writing and felt that the extended time I spent in this world was worthwhile.

*The acknowledgements section really shows how seriously Diaz took the research for the novel.
