Children of the Whales (Vol. 1) - Abi Umeda

On a sea of endless sand, the Mud Whale drifts slowly, home to a small, isolated community. Within its clay walls live two kinds of people: the Marked—those gifted with magical powers called thymia but cursed with shortened lives—and the Unmarked, who live long but cannot wield thymia. Sixteen-year-old Chakuro, the Mud Whale’s official archivist, has never seen the outside world. His life consists of recording events, watching people die young, and dreaming of distant lands.

Everything changes when he encounters a girl from another island—an outsider who brings with her death, revelation, and the truth behind their floating utopia. As long-forgotten secrets rise to the surface, Chakuro must decide whether to cling to the fragile peace of the Mud Whale or face the perilous reality beyond the sand.

Abi Umeda paints a breathtaking yet melancholic world full of mysticism, emotional weight, and philosophical depth in this acclaimed fantasy debut.
