Luminous will be out March 11, 2025.

Signed and personalized copies now available for pre-order at Yu & Me Books (New York, NY) and The Raven Book Store (Lawrence, KS)

Prescient yet timeless, perfect for fans of Klara and the Sun and We Are All Completely Beside Ourselves, this highly anticipated, sweeping debut set in a unified Korea tells the story of three estranged siblings—two human, one robot—as they collide against the backdrop of a murder investigation to settle old scores and make sense of their shattered childhood.

“I once had a family. At least, the earliest version of me had a family.”

In a reunified Korea of the near future, the sun beats down on a junkyard filled with abandoned robots, broken down for parts. Eleven-year-old Ruijie sifts through the scraps, searching for a piece that might support her failing body. There among the piles of trash, something catches her eye: a robot boy—so lifelike and strange, unlike anything she’s ever seen before.

Siblings Jun and Morgan haven’t spoken for years. When they were children, their brother Yoyo disappeared suddenly, leaving behind only distant memories of his laughter and near-human warmth. Yoyo—an early prototype of a humanoid robot designed by their father—was always bound for something darker and more complex. Now Morgan makes robots for a living and is on the verge of losing control of her most important creation. Jun is a detective with the Robot Crimes Unit whose investigation is digging up truths that want to stay buried. And whether they like it or not, Ruijie’s discovery will thrust their family back together in ways they could have never imagined.

At once a thrilling work of speculative fiction and a poignant exploration of what it really means to be human, Luminous is an unforgettably brilliant debut.
