Particulates is a new book of science fiction initiated by Rita McBride and edited by Nalo Hopkinson. The publication follows the spirit of McBride's Ways series and features 16 texts that are inspired by her 2017-18 laser installation Particulates at Dia:Chelsea in New York. Drawing on her longstanding interest in speculative thinking, the artist saw this exploration through science fiction and fantasy as a natural component of the installation itself.

Contributors include Gina Ashcraft, Elizabeth Bear, Samuel Delany, Minister Faust, Nicola Griffith, Nalo Hopkinson, Kameron Hurley, Victor LaValle, Karen Lord, Ken MacLeod, Annalee Newitz, Daniel Jose Older, Sofia Samatar, Vandana Singh and Mark von Schlegell.
