Polly's Really Secret Diary — Frances Thomas

Polly's had enough: her hamster‘s gone missing, her best friend isn't her best friend anymore, and the entire world is baby crazy! She's going to run away once she's saved up enough money and food. In the meantime, she's got to cope with school, an annoying little sister, parents who think she's going through a phase, and the fact that her ex-best friend is going to EuroDisney when Polly probably won't get a holiday at all! Life just isn't fair.
