For an elf who loves math, the hardest problems are people. Sagara must navigate ridiculous court etiquette, a complex ritual, and wartime...
Sagara hates the stupid rules of her elf society. She prefers the logic of math to wrestling with her grandmother's magical politics. When a rare sentient tree named Thea is kidnapped, Sagara joins her friends Millie, Petunia, and Max on a journey to the nearby Realm of Vanaheim to save her.
