Thief! By Malorie Blackman
Published by Corgi Childrens, 2004
You're the new girl in school. You're just trying to fit in - and it's not working. Then someone accuses you of theft, and you think things can't get any worse. Until you get caught in a freak storm . . .
The next thing you know, you're in the future. Being shot at for being out after curfew. You don't even recognise your hometown. And you're heading for a confrontation from your worst nightmare.
What if you could change the past to save the future?
