Cassandra Clare is bringing the Shadowhunters universe toward its close by changing who gets to lead the story. The Last King of Faerie, due from Knopf on November 3, begins The Wicked Powers, the final trilogy in a world Clare has been writing for two decades. Its protagonist, Drusilla Blackthorn, is a familiar character in a new role: no longer a child on the edges of the story, she’s stepping into an adventure of her own.
That shift also gives Clare room to write differently. With the end in sight, she says she can release the mysteries and possibilities she once held in reserve. In a conversation with Publishers Weekly, Clare reflected on what it means to finish the series, why Dru is suited to carry its final arc, and what she’ll miss when she leaves the world behind.
From a hoped-for debut to a sprawling world
Clare sold her first book in 2005, two years before City of Bones launched the Shadowhunters series. At the time, her goal was modest: she hoped the book would find readers and give her the chance to keep writing. The response exceeded that hope. Reader enthusiasm gave her the confidence to build the larger, interconnected world she had imagined but hesitated to pursue.
Over time, writing the books became a shared experience between Clare and her readers. Now, as she approaches the final trilogy, that long relationship carries mixed feelings. Ending the series feels creatively liberating, she says, but also brings the sadness of leaving behind a place and people she knows well.
A final trilogy without the usual guardrails
Clare sees The Wicked Powers as a chance to strip away a familiar safety net. In previous series, adults have intervened in the younger characters’ lives, either to protect them or obstruct them. This time, Clare wanted the young characters to face circumstances in which no one can step in to help.
The series’ position at the end of the Shadowhunters story also changes how she handles information. In an ongoing saga, she keeps some mysteries alive for later books. With the conclusion approaching, she can put more on the page now. “I don’t have to hold anything back,” she said of the freedom that comes with writing the final series.
Why Drusilla is the right person to lead
Dru first appeared in The Dark Artifices at 13. Clare says she wanted to establish her as someone who could eventually carry a story, while giving her a different starting point from earlier protagonists such as Clary and Tessa. Dru has no exceptional magical ability. She’s smart, stubborn, and a capable Shadowhunter, but she doesn’t begin with a special power.
As the youngest girl in her family, Dru is also accustomed to being overlooked and treated as a child. Clare wants her to grow into a leader by finding her own strength, rather than receiving a supernatural advantage from the outset. That makes Dru’s coming-of-age central to the final trilogy’s perspective on heroism.
Leaving the characters behind
Clare expects to miss the characters most. After years of writing them, she knows how they think and behave, which makes returning to them feel natural. The world itself has become a familiar place, too, even though ending it is her choice.
The trilogy’s titles signal the scale of the ending: The Last Shadowhunter, The Last Prince of Hell, and The Last King of Faerie. Clare describes the experience as bittersweet, and says the emotions help her write characters facing the end of something immense. Her final Shadowhunters stories draw on that shared sense of farewell, with Dru’s growth at their center.
