At the moment, no.We would love to, but its' pretty long and we don't have enough free time. Also, if we do, it will be written in italian and we'll be in need of somebody that would like to translate it to finally be in english :)
All that we know about the story is scattered in this site and various asks on "Shifterask".We also write pieces of the story every time that we post a drawing about the shapeshifter au, in the description. You can find them all in the "Overdrugs-mayhem" tumblr under the tag "OW Shapeshifter AU"
We gathered all the fanfiction that other people produced in this site, at the "fanwork" page.
The story is all in our head, still unwritten and unpublished. It may or may not take written form in the future but who knows! D:
For now all that we can give you are the main event that we planned!
