Judith Rumelt, known professionally as Cassandra Clare, is an American author celebrated for her young adult fantasy novels, most notably The Mortal Instruments series. Born in Tehran, Iran, to American parents, Clare's early life was marked by extensive travel across Europe before she settled in Los Angeles and later New York City, where she worked in entertainment media. She is a friend of author Holly Black, with whom her works sometimes share characters and narrative elements. Clare's writing career has garnered significant commercial success, though it has also been accompanied by accusations of plagiarism related to her earlier fan fiction work and a lawsuit concerning similarities to another author's series. These controversies did not prevent her books from becoming bestsellers and receiving numerous awards, particularly for "City of Bones."

This expansive series includes multiple trilogies like The Mortal Instruments, The Infernal Devices, and The Dark Artifices, as well as companion books and graphic novels. Clare's publisher has also implemented innovative marketing strategies, such as the "City of Fallen Angels treatment," to boost physical book sales. As of 2013, she resides in Amherst, Massachusetts.

Cassandra Clare's primary contribution to literature is the expansive "Shadowhunter Chronicles," a shared universe featuring a variety of interconnected series. The foundational series, "The Mortal Instruments," introduced readers to Clary Fray and Jace Wayland in contemporary New York City. This was followed by the prequel trilogy, "The Infernal Devices," which transported readers to Victorian London. Clare, often collaborating with Sarah Rees Brennan, has continued to expand this world with "The Dark Artifices," set in Los Angeles, and "The Last Hours," among other series. These narratives explore the lives of Shadowhunters, beings who protect the human world from demons, and often involve complex relationships and supernatural conflicts. The series has been adapted into film and television, though with mixed success. Companion books and graphic novel adaptations, many co-written with Brennan, further flesh out the lore and characters within this popular young adult fantasy setting.

Her style is characterized by fast-paced plots, intricate world-building, and a focus on young protagonists navigating complex emotional and supernatural challenges.

Cassandra Clare's career has not been without controversy. She faced accusations of plagiarism stemming from her early fan fiction work, "The Draco Trilogy," and was banned from FanFiction.Net for her practices.
