Kor has five days to save his village, help a lost stranger, and impress a haughty girl.

From the moment Kor and high-born Ilyssa find a wingless boy, they’re bound for adventure. Braving the perils of a savage land, they’ll meet monstrous marauders, invisible watchers, legendary warriors, deadly bugs, and a shaman who commands the sky.

But a final test awaits within the Cave of the Gods, where secrets will shatter their beliefs about people, gods, and the world.
