The Night Court will not stand idly by while innocents are attacked. But with Prythian still piecing itself together in the wake of the devastating Hybern War, the task of uniting is proving more difficult by the day.

To make matters worse, those who rule and protect the Night Court are reeling from recent betrayals and revealed truths. The rifts dividing them seem insurmountable.

But to defeat Koschei's creeping shadow, they must find a way back to each other and resurrect their former alliances. To survive, they must find a way to repair the splintered harmony all around them.

Sarah Janet Maas (born March 5, 1986) is a #1 New York Times bestselling American author who has fundamentally shaped the modern "romantasy" genre. Born and raised in Manhattan, Maas spent her childhood exploring museums and reading global fairy tales, though she often felt frustrated by the lack of fierce, compelling heroines in fantasy literature. Drawing inspiration from strong pop-culture figures like Buffy the Vampire Slayer and Sailor Moon, she began writing the stories she wanted to read.

At sixteen, Maas started drafting a dark twist on the Cinderella fairy tale—imagining her not as a servant, but as a deadly assassin. She serialized the story, originally titled Queen of Glass, on the writing platform FictionPress, where it quickly became one of the site's most popular works. She continued developing her craft at Hamilton College, graduating magna cum laude in 2008 with a degree in creative writing and religious studies.

Her debut novel, retitled Throne of Glass, was published by Bloomsbury in 2012 and became a massive international hit, ultimately spanning an eight-book epic series. In 2015, Maas launched her second major series, A Court of Thorns and Roses (ACOTAR). Initially a loose retelling of Beauty and the Beast, the series transitioned her work into the "new adult" and adult fantasy spaces. The ACOTAR series became a viral sensation, largely driven by massive popularity on TikTok. In 2020, she introduced her third ongoing adult urban fantasy series, Crescent City.

With over 75 million copies sold worldwide and translations in nearly 40 languages, Maas stands as one of the most successful contemporary authors. She currently lives in Pennsylvania with her husband, whom she met in college, and their two children.
