Thief! 

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?
