Very vague question

[Topsie]

Does anyone have an idea what this book might be I remember reading it when I was younger .... However, I am very vague on the details.

Its about twin girls whose parents move I think to a house and there is a tower where they have their bedroom.

One of the twins finds a cloth doll in a shop and is really attracted to it and ends up buying it and weird things start to happen and its because of this doll but she cant get rid of it.

I also think something happens and one of the girls breaks their leg but thats not definate.

Thanks

is this a scary one where the doll comes to life and she has to keep it til shes older, if it is I think I've read it if not, just ignore me!
