For an elf who loves math, the hardest problems are people.
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.
Sagara must navigate ridiculous court etiquette, a complex ritual, and wartime negotiations in a world where even the most basic laws of nature have been twisted out of true. Can she find a way to use both math and magic to save Thea and all of Vanaheim?
