Shadow Queen

Can someone explain to me what a Mary sue is?  I want to write a story,  for once, but I've seen some stories get called out for being  Mary sue-ish. I really don't want that.  

Herro?

I'm thinking of writing a story but I don't know what about.  Can anyone give me an idea? I could also make a drawing book if you'd like just ask me what to draw and I'll try to draw it
