His only hope is to join with the Division, but they have plans of their own, and it's the last thing Aern is willing to do. Emily just wants her sister back. She doesn't care about the prophecy, or know what's at stake. But when she goes after Aern, the truth of the matter uncoils, and Brianna isn't the only one who's in danger. Suddenly, they're at the center of a secret war, and unless they can work together, they'll both have a sacrifice too big to make.
