From the author of The Night Library of Sternendach comes a haunting sci-fi horror for fans of Jeff VanderMeer and Lina Rather. Dr. Therese Blake is a homebody archaeologist devoted to the history of planet Earth. But when her sister Lissy makes a stunning discovery near an abandoned colony on a distant exoplanet, the sisters team up to discover its secrets. Eerie, luminescent images cover the walls of an underground cavern. The glass garden looks like a payday to Lissy, who’s been struggling to turn a profit to keep her salvage crew fed and paid. Therese, however, insists on careful academic procedure. She can’t figure it out: Is the anomaly an artificial creation-or a living organism? As the anomaly’s mystery draws the sisters into an obsessive orbit, it turns out neither greed nor science can offer protection from its relentless gravity.
