Product description

Marty and her sister Melissa couldn’t be more different.

“That’s the worst thing about my sister. She NEVER misses a chance to wind me up.”

Football-mad Marty loves her Converse and helping her dad with his DIY. Melissa, however, loves all things pink and girly.

So it comes as no surprise that when they have to share a bedroom, Marty and Melissa struggle to get along.

But all that changes after a terrible accident, which helps the sisters realise they are closer than they thought…

From bestselling author Jacqueline Wilson, The Worst Thing About My Sister explores sibling rivalry and the importance of family.

The Worst Thing About My Sister is full of fun, frolics and little pearls of wisdom. Here she focuses on that old family chestnut – sibling rivalry – and gives quarrelling sisters plenty of food for thought – Blackpool Gazette

    I very much liked this book. It was very funny and expressed how to the relationships between two very different siblings( or even just people in general ) argue. In my opinion its a very good book and I would recommend it.

    I think that this book is awesome. I loved it.This book is about two sisters called Marty and Melissa.Marty is rather boyish and likes animals,football, and her converse trainers.She hates dresses. Melissa is all things pink, shes really girly and likes Justin Beiber. Basically they are complete opposites.They fight all the time.But then whilst fighting, one of the sisters gets hurt. Will her sister be there for her? Find out in The worst thing about my sister.5/5. <3
