What the Zebstrika said c: If you expose it to them, and there's a chance they'll like it, they'll eventually catch onto it. If they really just don't like it, then they simply won't.
Btw we've got the Books prefix back in E&M now (since nobody used it in FF&W). Does anybody, uh, read? My dad thinks I read too little so he dumped some books onto me and said Read Them, They Are Good so I guess I will ahah. This particular trilogy is called Stjärnklart, Stjärnfall and Stjärndamm and they are obviously Swedish and about something apocalypse aliens something soemthing. Might be cool.
