On the day of Saskia's kenning - a special bone reading that determines the apprenticeships of all seventeen-year-olds - her worst fear comes true. She receives an assignment to train as a Bone Charmer, a seer, like her mother.
Saskia knows her mother saw multiple paths for her, yet chose the one she knew Saskia wouldn't want. Their argument leads to a fracture in one of the bones, with the devastating result of splitting Saskia's future.
Now she will live her two potential paths simultaneously: one where she's forced to confront her magic, and one where she tries to run from it. But when both paths become entangled in the plot of a rogue Charmer, Saskia learns that no future is safe, and some choices have unimaginable consequences. Only one future can survive. And Saskia's life is in danger in both.
