Steffi has been a selective mute for most of her life. But Rhys, the new boy at school, sees her. He's deaf, and her knowledge of sign language means she's assigned to look after him. To Rhys it doesn't matter that Steffi doesn't talk and, as they find ways to communicate, Steffi finds that she has a voice, and she's falling in love with the one person who makes her feel brave enough to use it.
