At the Angle of Blue (Hardcover) (ISBN-13: 9798999461759)

High in the Murshida Range, where the snow does not know the word for melting, a stream begins. In a city far below, in a corporate laboratory above the pre-dawn lights of Purgatum, a chemist named Joy Altan creates a blue that should not exist-a color held not by pigment but by the sustained geometry of a single, impossible molecule. It is the finest dye she has ever produced. By the afternoon of the day she presents it, the color is already beginning to bloom beneath her own skin.

Joy has built her career at Chromatera, the corporation whose dyes define the season's fashion. Her promotion to Senior Heritage Chemist is days away. The launch of Azuline, Chromatera's most lucrative product, is on the runway. And then she goes home to Pergamum, the coastal village on the Mederean Sea where her grandmother still keeps the teapot ready at the kitchen table.

The villagers have turned blue.

The dye she invented has been seeping into the water for a decade. It tints the skin at the wrists and the throat, deepens at the knuckles of the sorting women, settles in the hands of the elders who have washed in that water all their lives. And yet-by a mechanism no one has thought to look at-the same molecule that is poisoning the water is also keeping the elders alive. Her grandmother among them. To stop the dye is to kill the people who need it. To keep the dye is to kill the people it has already begun to poison. Joy is the chemist who built the trap, and Joy is the chemist who will have to find a way out of it.

The way out is in her late grandfather's notebooks-a chemistry he was building, before he died, in a different direction. A chemistry that does not poison the water it comes from. As Joy reconstructs his work and discovers a second, hidden Chromatera facility she was never meant to find, she also begins to understand what her grandmother has been quietly teaching her since childhood: that there is another way of holding color, older than the laboratory and stranger than the chemistry her training prepared her for.

At the Angle of Blue is a novel about chemistry and inheritance - and, beneath all of its other concerns, a love letter to water. To its patience, its memory, and its quiet insistence on returning to itself.
