A silenced song

Have you ever heard of the Dark forest? Well in the Dark forest there live dark and dreadful creatures called goblins. The goblins are ugly, both inside and out. Their skin is slimy green, they have horns that are oil black, claws that could rip you open with no effort at all. And worst of all is their hearts who are blacker than the darkest night. But are all goblins really that bad? Can't there be good goblins like there are bad humans or cruel horses?
This is the story of a little goblin girl that is a little bit different from all the other goblins and how her beautiful song is silences at last.
