Shadowstalker — Emily L. Goodman

When Annie is faced with the last person she expected to see alive, it could devastate her--but she doesn't have time for that. Cyan is at it again, this time with an act of evil so vile that it terrifies everyone who hears about it. This time, the Cavemage knows that she has to stop him--but she also knows that the people of Luria need hope more than anything. They no longer believe in the Cavemage, and a few people saved won't change that; so Annie gives them a new legend to believe in. She creates the Shadowstalker, who appears out of nowhere when Luria's people are at their darkest. She doesn't speak to many; but wherever she goes, she leaves light in her wake.
