Emily Saunders knows what career she'll have, who she'll marry, and even how many children she'll have. She's known this since she was born. All thanks to the scientists who created the community of Theoria and decided planning out the future and eliminating chance by using people's blood is the best way to live.

Everyone is happy. Except Emily. But since her dad is one of the founding scientists, leaving Theoria is impossible. Worse, Emily starts getting visions of the future—a future that doesn't fit what the scientists have planned. She has to hide her gift or she could be killed by the very people who are claiming to know the way to a peaceful existence. And when a stranger comes into the community and has the same gift, it threatens to expose them both.

But the biggest secret is the one Theoria's founders are keeping. Their experiment is so much greater than they're letting on, and it could mean the end for Emily and everyone she cares about.
