McGuire has released more than forty short stories and novellas set in the October Daye universe. Some are available through anthologies alongside authors such as Charlaine Harris, Kelley Armstrong, and Tanya Huff.[11][12] Others are available as bonus content in the print editions of her books (beginning with Once Broken Faith),[13] her website,[14] and to her Patreon subscribers.[15]

The short stories typically explore alternate character points of view and form their own story arcs over multiple installments. Recurring narrators include love interest Tybalt; Toby's Firstborn aunt the Luidaeg; and characters in the Lorden family.[15] Other one-off stories continue events of the novels from minor character perspectives.

The October Daye series has appeared on the New York Times Best Seller list.[16]

Publishers Weekly calls the books "a pulse-pounding, often surprising tale"[17] and "a tightly plotted adventure."[18] The magazine says of Night and Silence, "McGuire continues to put her heroes through harrowing emotional and physical dangers while peeling back more layers in an increasingly complicated mythos. There are significant payoffs for longtime readers as she calls back to numerous elements from previous books. Toby’s combination of pragmatic heroism and relentless self-destruction makes her a compelling heroine in a secret folklore-filled world that still feels fresh and dangerous after all this time."[19]

American actress Felicia Day says it is, "Top of my urban-paranormal series list!"[20]

The first nine books were originally published as mass market paperbacks. Book Ten, The Brightest Fell (2017), was the first volume released in hardcover.

In 2019, DAW Books released a Rosemary and Rue 10th Anniversary Special Edition that included a new bonus novella, "In Stranger Courts."

The first three books of the series have been translated to German.[26] The first two books are available in French.[27]
