From the writer of Confessions of A Teenage Drama Queen and My Worst Best Friend comes this hugely entertaining teen read, all about what it really means to be a girl. ZiZi likes to think of herself as a girly girl: her wardrobe is almost exclusively pink, her daily makeup routine can take upwards of an hour and she loves a bit of a flirt. Her best friend Loretta is very different: all of her clothes are black, she doesn't wear any makeup whatsoever and she doesn't like the way ZiZi dumbs herself down for boys – or her old-fashioned ideas about "a woman's place". One day, they decide to make a bet. Can ZiZi stand looking like Loretta for longer than Loretta can bear dressing like ZiZi? As their summer unfolds – often hilariously – the pair are surprised to find they have a lot to learn from each other.
