The Dream Runners by Shveta Thakrar

Seven years ago, Tanvi was spirited away to the subterranean realm of Nagalok, where she joined the ranks of the dream runners: human children freed of all memory and emotion, who collect mortal dreams for the entertainment of the serpentine, immortal naga court.

But when one of Tanvi’s dream harvests goes awry, she begins to remember her life on earth. Panicked and confused, she turns to the one mortal in Nagalok who might be able to help: Venkat, the dreamsmith responsible for collecting the dream runners’ wares and shaping them into the kingdom’s most tantalizing commodity. And as they search for answers, a terrifying truth begins to take shape—one that could turn the nagas’ realm of dreams into a land of waking nightmare.
