With her sister’s help, she can squeeze through the tests and get access to the information she needs to find "her" demon. To take back what was stolen.Then she meets Carter. He’s cute, smart, and she can borrow his magic, too. He knows her secret—but he also has one of his own. Suddenly, Penelope’s impossible quest becomes far more complicated. Because Carter’s not telling her everything, and it’s starting to seem like the demons have their own agenda…and they’re far too interested in her.
