Seize the Parallel [EPUB ebook] 

PARALLEL UNIVERSES HAVE THEIR OWN RULES.
High school senior and amateur physicist Audie Masters has done what no other physicist has ever done before her: discovered a parallel universe. She’s also found a parallel—and very different—version of herself.
Now what?
As Audie struggles with the dangerous effects of traveling to a parallel universe, now she wonders if she’s gone too far.
Can what she did be undone?
Will she ever reclaim her life as it used to be?
