Taylor, Sam, and Sophie have been best mates forever. But lately things have been changing. Taylor is starting to sense that maybe Sam and Sophie would rather hang out only with each other instead of with her. And she can't talk to her mum about it -- Mum's been acting even more depressed than usual, spending the day watching telly in her bathrobe and eating only when Taylor makes her dinner.Then one day, while out shopping, Taylor meets Kat, an aspiring model who's got dozens of older blokes following her around. Taylor can't believe this glamorous girl wants to be her friend, but she's willing to do anything to keep Kat interested. The problem is that Kat loves to shop, and Taylor realizes that if she wants to hang out with Kat, she'll have to come up with the money to keep Kat happy...even if that means going against everything Taylor knows is right.
