Sunbirth by An Yu; 2025. Hardcover.

A young woman keeps one apprehensive eye on the sky above as she tends the pharmacy of traditional medicine that belonged to her great grandfather. She has few customers, and even fewer visitors: her older sister Dong Ji, her last living relative, works at a wellness parlor across town for those who can afford it—which, during these strange and difficult days, is not many. Five Poems Lake had fallen on hard times long before the sun began shrinking, but now, every few days, a new sliver disappears. As the temperature drops and the lake freezes over, the population of the town realizes that they will soon die—if not of the cold and starvation, then of despair.

When the Beacons begin to appear—ordinary people with heads replaced by searing, blinding light, like miniature suns—the town’s residents wonder if they may hold the answer to their salvation, or if they are just another sign of impending ruin. A photograph belonging to their father, who died mysteriously twelve years ago, may offer a clue in the mystery of the Beacons, and Dong Ji and her sister wonder if they may finally learn what happened to their father.

in Sunbirth, An Yu honors the unique relationship held between sisters and asks how much we can ever know about the deepest mysteries of the world.
