A quiet kind of thunder

Steffi doesn't talk. Rhys can't hear. They understand each other perfectly. Love isn't always a lightning strike. Sometimes it's the rumbling roll of thunder ... Steffi has been a selective mute for most of her life - she's been silent for so long that she feels completely invisible. But Rhys, the new boy at school, sees her. He's deaf, and her knowledge of basic sign language means that 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 does have a voice, and that she's falling in love with the one person who makes her feel brave enough to use it.
