The Worst Thing About My Sister (Hardback)

Being a sister isn’t always easy – but what’s the worst thing about yours?

Marty and her sister Melissa couldn’t be more different. Tomboy Marty loves playing football, hiding in her secret den and helping with DIY. Meanwhile, Melissa loves Justin Bieber and all things pink, girly and pretty. These chalk-and-cheese sisters usually get on, despite their occasional scraps. But that all changes when Mum tells them they have to share a room! For Marty, sharing a bunk and losing her private sanctuary turns out to be the very worst thing about having a sister. But when disaster strikes, the girls discover that being too close for comfort can have unexpected benefits. Will they finally have the chance to become not just sisters, but true friends?

  • Very good book. Seems as if Jacky has gone through the same thing! But it is actually true: most sisters don’t relate TOO well. Laughing together one minute, fighting the next!
