Jess Not the Same [EPUB ebook] 

Jess is desperate to be with Jason, the boy she loves. Too bad he lives in another reality.
After enlisting her mother’s help to create a device that will allow her to switch places with her alternate self, Jess finally gets her chance to be with the boy of her dreams.
There’s only one problem. Jason is already dating another girl. A girl who happens to be Jess’s new step-sister.
Can Jess get them to break up before the big dance? If she can, will Jason even want to be with her?
While Jess is focused on her boy troubles, more sinister things are going on behind her back that might render her plight meaningless.
