Investigative journalist Sarah Sharma is haunted by whispers in Delhi's twilight streets, where contemporary skyscrapers dance with ancient shadows. She is drawn into a maze of secrets by a string of deaths-bodies contorted into unfathomable angles, eyes frozen in silent screams. Every route leads to the foggy Vayu Psychiatric Hospital in the far-off Garhwal hills, where Sarah's brother Anil disappeared six years ago. When she finds a glowing blue substance that connects the victims-and possibly her brother's fate-what started out as a professional investigation devolves into a personal obsession. Sarah uncovers a horrifying reality as she dissects conspiracy theories: a pharmaceutical behemoth has produced a substance that goes beyond medicine and changes its users into something less-and more-than human. The architect of this evolutionary nightmare must be confronted by Sarah before his vision becomes uncontrollable, as the city's powerful elite closes in and her own allies divulge dangerous secrets. Once awakened, some shadows eat the light that reveals them.
