@MadyElly No you should not and should never have done it. You're breaking the law, you see even though you credited the author that only is valid on fanfiction. Posting the actual story is not only wrong but it's against an international law. See only the author, the owner of the book and their publisher who bought the right from the author to distribute that book can post it anywhere online at any time. Unless you have a legal document from both Simone and her publisher you are breaking the law by posting Perfect Chemistry. This doesn't just apply to Simone it goes for any written work by any writer.
Simone even has an account on Wattpad now and she's posting an excerpt of Perfect Chemistry there.
I think it is fair to warn you that I've reported the book and you've probably got 24 hours before Wattpad takes it down. Consider yourself lucky it''s just that because copyright infringement is a really serious crime.
Just stick to posting the stories you're the author of there is nothing about that, that gets you or Wattpad into trouble.
