In concise and distilled prose, Lemus presents a collection of still lifes, landscapes, and portraits of a challenging year that threatened all she loved most.

There are only a few words per page in Particulate Matter, but that doesn't actually matter. The words Felicia Luna Lemus does carefully choose serve to paint a brilliant picture of her marriage, of a Los Angeles covered in ash, of dashed hopes and new beginnings.
--Good Morning America

A love story that's profoundly rooted in the emotional, geographical, and sociopolitical terrain of today...Like song lyrics or snapshots, [Lemus's] wisps and fragments of language take on a coded and otherworldly atmosphere, one that conveys wonder and dread almost subliminally...Particulate Matter is a moving example of how to write about climate change, not didactically, but with the deep impact of both personal loss and literary elegance.
--NPR Books

A tiny, powerful flame of a book. Lemus' writing lands like sparks and ash, fragmented and tinged with grief...Particulate Matter is...an exploration of the simultaneity of delight, yearning, grief and confusion of being in love with a person and a place. Of being alive at all.
--San Francisco Chronicle

Lemus has a particular talent for engaging the deepest and most complex parts of the self with the simplest turn of phrase. Detailing the toughest year of her life, she uncovers meaning in the ordinary and the terrifying.
--Ms. Magazine

What distinguishes Lemus's book...is how the nightmare lived by one California couple became, in the summer of 2020, the nightmare lived by much of the West Coast. This makes Particulate Matter not just a memoir but also an oracle, foreseeing the present as we repeat, en masse, a similar ordeal, separated from loved ones and watching the sky rain apocalyptic ash, telling ourselves, as Lemus does, 'I almost believe this...will end someday.'
--Alta Magazine

An unforgettable meditation on [Felicia Luna Lemus's] experiences...Lemus bears an unmatched precision of the craft. This succinct mic drop of a personal story begs to be read over and over again."
--Booklist

With playful and warm prose, Lemus takes readers into the most difficult year of her life and marriage. Set in Los Angeles, it chronicles her [spouse's] sudden and serious adult-onset asthma, and the literal and figurative fires that raged that year over their lives.

A [book] about finding beauty in the most challenging and terrifying times.
--Lambda Literary

Particulate Matter is the story of a year in Felicia Luna Lemus's marriage when the world turned upside down. It's set in Los Angeles, and it's about love and crisis, loss and grief, the city and the ocean, ancestral ghosts and history haunting. Nature herself seemed to howl. Fires raged and covered the house Lemus and her spouse shared in ash. Everything crystallized. It was the most challenging and terrifying time she had ever experienced, and yet it was also a time when the sublime beauty of the everyday shone through with particular power and presence.
