ead-spinning epic about three friends on a quest to protect the world from a threat as unknowable as it is terrifying, from the Nebula Award-winning and New York Times bestselling author of Annihilation, Jeff VanderMeer.

Jonathan Lambshead stands to inherit his deceased grandfather's overstuffed mansion--a veritable cabinet of curiosities--once he and two schoolmates catalog its contents. But the three soon discover that the house is filled with far more than just oddities: It holds clues linking to an alt-Earth called Aurora, where the notorious English occultist Aleister Crowley has stormed back to life on a magic-fueled rampage across a surreal, through-the-looking-glass version of Europe replete with talking animals (and vegetables).

Swept into encounters with allies more unpredictable than enemies, Jonathan pieces together his destiny as a member of a secret society devoted to keeping our world separate from Aurora. But as the ground shifts and allegiances change with every step, he and his friends sink ever deeper into a deadly pursuit of the profound evil that is also chasing after them.
