Lissa's world has just turned upside down. Her father has been in jail and is coming home for Christmas. She can't bear the way her mother and sister are so happy and making welcome plans. After all, he was the one who let them all down and spoilt her life, wasn't he? Before he went to jail, they had a nice house, she had trendy clothes and pretty much anything that she wanted, but now she is taunted by her classmates.

Life only gets better when new girl Diane arrives at school. Diane sympathises with Lissa and doesn't make fun of her dad. But Lissa doesn't realise that Diane is manipulative. And she doesn't realise either how much her dad loves her. It is only when a combination of events come together that she has to face facts about who and what are really important to her.
