Dagny embarks on what seems like a straightforward quest: to recover her family's herd of reindeer, stolen by a troll and taken into a mystical Scandinavian forest. And she intends to use a straightforward sort of magic for the job: elven rune magic that her father taught to Dagny and her brother. But to survive an encounter with a dangerous shadow creature in the forest, Dagny must discover her own powers are beyond anything she was taught, and she must confront what could present the most danger of all: the wild spirit inside herself.
