The highly anticipated, explosive conclusion to the Ninth House trilogy from #1 New York Times bestselling author Leigh Bardugo.

Hell is empty and all the devils are here…

Alex Stern made it to hell and back more than once, but this time she left the door open behind her. Demons are creeping through the streets of New Haven and the Yale campus, feeding on the souls of the living, terrifying the dead. Alex and her allies can hunt them, but it’s only a matter of time before the gates to the underworld open and they face a war they cannot win. To stop it, they’ll have to reach deep into the secrets of Yale and its societies, and discover the truth hidden in Alex’s own blood.

While she struggles to hold onto the dream of a future Yale once offered, Alex must contend with the machinations of a corrupt Lethe Board and a deadly vampire with his own connection to the societies. But for the first time in her life, she won’t have to face the fight alone. Dawes, Turner, Mercy, and even Tripp will have a role to play, none more so than Alex’s mentor Darlington, the golden boy who lived so long in her head, now back in the flesh and cursed with dangerous powers of his own. Hell itself is stalking the delegates of Lethe House, and they’re all about to learn that demons don’t play by human rules.

In the Alex Stern series, the boundary between life and death is thinner than you think—and for Alex, it’s a line she’s learned to walk.

Read full series description

Set in a world where the supernatural lurks just beneath the surface, Leigh Bardugo’s Alex Stern novels weave a gripping narrative of magic, mystery, and the complicated morality of a universe brimming with secrets. At the heart of the series is Alex, a flawed and fierce young woman with a gift she never asked for: the ability to see ghosts. This extraordinary power thrusts her into a world of hidden societies and arcane secrets, where the line between right and wrong is constantly shifting.

Bardugo’s world-building in Alex Stern is as lush and atmospheric as it is haunting. From the hallowed halls of Yale to the shadowy corners of the occult, every setting is rich with history and danger. But it's the complex characters that truly bring the story to life. Alex, with her troubled past and her complex relationships, isn’t just a survivor—she’s someone you can’t help but root for, even as she navigates a world that demands impossible choices.

The Alex Stern series is part urban fantasy, part dark academia, and part psychological thriller—seamlessly blending all these elements into a tale that never lets you breathe easy. Bardugo explores themes of power, identity, and the haunting effects of trauma, all while keeping readers on the edge of their seats with every twist and turn.

If you crave a story that mixes the supernatural with the psychological, the eerie with the emotional, Alex Stern offers a journey that is as darkly mesmerizing as it is unforgettable.
