This is a sequel so I suggest you read Changed first. Cat and Jade get back to America, and start another year at school, where there is a surprise waiting for them. Everyone is shocked when they see how different Jade is, and try to get used to it, but it won't be easy.
Liam and Niall try to enjoy life without the girls, and have to make do with long distance phone calls, but it's tearing them apart. Harry is in pieces without Anna, but refuses to call her, because he doesn't want to ruin her relationship with Ashton. Then the boys see an advert that could change everyone's lives forever...
