Wren can do things that other people can only dream of. Make it snow on a clear, crisp day. Fly through an abandoned tunnel. Bring a paper bird to life. Wren knows her abilities are tinged with danger—knows how easy it is to lose control—but she can't resist the intoxicating rush. And now that she has Gabriel by her side, someone who knows what she can do—what she has done—she finally feels free to be herself. But as Wren explores the possibilities of her simmering powers, Gabriel starts pushing her away. Telling her to be careful. Telling her to stop. The more he cautions her, the more determined Wren becomes to prove that she can handle things on her own. And by the time she realizes that Gabriel may be right, it could be too late to bring him back to her side.
