Spear of Courage - A. C. Ward - Bog

She needs help, but at what cost?

Finally surrounded by people she cares about, Shou begins to embrace her new life. Her friendship with Masaru, the heir to the Date clan, intensifies as they travel in search of allies. Forming alliances is her only chance against the family that's hellbent on killing her. But when a new enemy targets Masaru instead of Shou, everything changes.

Determined to save him, Shou refuses his protection and sets out on her own. With a more sinister and darker force threatening them, nobody can help-not even her kami friends. Torn between the human world and her duty to the gods, Shou must sacrifice everything for the one she loves. But will she pay the ultimate price for doing the unthinkable and turning on the kami?

The third book in The Kami Prophecy, a YA fantasy set in a world based on feudal Japan.
