Queen of Air and Darkness is the third and final book of the The Dark Artifices trilogy.
What if damnation is the price of true love?
Innocent blood has been spilled on the steps of the Council Hall, the sacred stronghold of the Shadowhunters. In the wake of the tragic death of Livvy Blackthorn, the Clave teeters on the brink of civil war. One fragment of the Blackthorn family flees to Los Angeles, seeking to discover the source of the "blight" that is destroying the race of warlocks. Meanwhile, Julian and Emma take desperate measures to put their forbidden love aside and undertake a perilous mission to Faerie to retrieve the Black Volume of the Dead. What they find in the Courts is a secret that may tear the Shadow World asunder and open a dark path into a future they could never have imagined. Caught in a race against time, Emma and Julian must save the world of Shadowhunters before the deadly power of the parabatai curse destroys them and everyone they love.

- Limited first edition: The first printing edition of the book (English, North American edition) is set to be the only exclusive, special edition printed for the book. It contains ten black and white illustrations, a full color poster printed on the back of the book jacket by Alice Duke, and a short story (A Love That Never Tires) that functions as a sequel to A Long Conversation.
- The book picks up right where Lord of Shadows left off, though there was originally supposed to be a time jump of about a week. The main events of the book spanned about a week, with one part taking place around three weeks after the main story, and the epilogue taking place about two weeks after.
- The title is a reference to the poem Her Strong Enchantments Failing by A.E. Houseman. It can also refer to Mab, Queen of the Faeries in Romeo and Juliet, amongst other folklore.
- As with Lady Midnight and Lord of Shadows and its eponymous characters, there is a character called "Queen of Air and Darkness": Annabel Blackthorn.
- Annabel is also featured on the cover. She is wearing a red dress, which in Shadowhunter tradition is "to call enchantment down," and has no runes, a reference to a certain section in the book. Like the previous Dark Artifices installments, the character on the cover is also underwater. The backdrop features a distorted image of ruined skyscrapers, and a ruined highway.
- Cristina Rosales will be featured on the spine of the book, marking the first instance where the cover and spine characters differ. Mark Blackthorn was originally intended to be on the spine, but this was later changed, in part because the publisher was unwilling to feature a male character on a book with the word "Queen" in the title.
- This book is told from several points of view, namely: Emma, Diana, Helen, Mark, Cristina, Kit, Julian, Diego, Dru, Ash, Jace, Alec, Manuel, Kieran, Clary, Magnus, and the Seelie Queen.
- The book was initially slated for release in 2019, after Chain of Gold, but in September 2017, it was announced that the release order of the two novels was switched, partly because of writer's block on Chain of Gold but also because the publishers "wanted to keep the momentum from Lady Midnight and Lord of Shadows going."
