Ash and Aiden Delatour are identical twins, living a privileged lifestyle with loving parents. In a world that has fallen apart at the seams, they want for nothing. All they have to do is be there for each other, no matter what. But after Aiden suffers a terrible injury, he isn't the same brother Ash always relied on. Something has changed, and it will lead to a discovery that will turn their whole world upside down. A brilliant and timely middle-grade novel from the bestselling author of My Life As An Alphabet and A Song Only I Can Hear.
