Official novels set in the world of The Magnus Archives are on their way!
Random House Worlds, an imprint of the Random House Publishing Group, a division of Penguin Random House is thrilled to announce a new collaboration with the massively popular horror fiction anthology podcast The Magnus Archives.
On October 27, 2026, Random House Worlds will publish From the Library of Jurgen Leitner, a thrilling prequel novel written by the hit podcast’s creator Jonathan Sims and Nebula, World Fantasy, and Aurora award-winning author Premee Mohamed. From the Library of Jurgen Leitner explores the most infamous institution in the podcast’s universe for the first time—the perilous private library of the enigmatic collector Jurgen Leitner, where esoteric books are guarded and researched at a fatal cost.
With more than 300 million downloads worldwide since its debut in 2016, The Magnus Archives has garnered a devoted global fanbase, earning widespread acclaim and winning over 30 awards for its deeply unsettling storytelling, intricate supernatural mythology, and standout voice performances. The Magnus Archives is created by independent media production company Rusty Quill and distributed by Acast.
In this uncanny eldritch horror novel, two employees from different eras attempt to uncover the library’s secrets. Though their tenures at the library were years apart, their stories unfold in parallel, and their footsteps echo down the same eerie aisles, caught in a web spun long before either ever heard the name “Jurgen Leitner.” Will they find a way out… or will the library consume them before it’s too late?
Will you be pre-ordering From the Library of Jurgen Leitner?
