The Worry Tree by Marianne Musgrove

Just because something's not magic doesn't mean it can't be magical ...

Juliet's a worrywart, and no wonder! Her little sister, Oaf, follows her around taking notes and singing 'The Irritating Song' all day long. Her parents are always arguing about Dad's junk. Juliet's friends, Lindsay and Gemma, are competing to see which one of them is Juliet's best friend.

And then there's Hugh Allen ...

Juliet can't fit in any more worries!

But then she makes a remarkable discovery. Behind the peeling wallpaper in her new bedroom, Juliet uncovers an old painting of a very special tree a Worry Tree . So with the help of a duck called Delia and all the other Worry Tree animals, Juliet just might be able to solve some of life's big problems!
