So, I read the book mid to late 90s, multiple times and for the life of me cannot remember the title. The plot goes a little something like this:
Girl moves to a new town (I think it's set in the UK). She befriends a girl Rosie (?). Rosie has red hair, her family is Irish. They are not very well off. She's a troublemaker in school. The story moves back and forth from past to present. Basically Rosie dies after falling/being pushed in front of a lorry. The story is told from after her death and from the build up to her death. I think the two girls fell out, possibly the friend pushed her in front of the lorry? Not sure. Also, the girl ends up dating Rosie's brother which may have formed part of the falling out.
The details are hazy so I'm not sure about anything I've said. I think the book cover was white and had blood on it.
Anybody familiar with it? It's driving me crazy.
