Caitlin Starling is the author of The Luminous Dead. It's a paranoia-drenched sci-fi tale that follows a young woman named Gyre on a solo expedition into an enigmatic cave system on a far-off planet. Her only companion is Em, a mysterious and often untrustworthy benefactor who guides her from afar via a high tech caving suit. Em's motives, Gyre's history, and the terrifying secrets of the cave tangle in this claustrophobic and emotional decent into discovery and delirium. The Luminous Dead is available now from Harper Voyager.
