the premise-take 2

I'm going to buy a ton of books for the school library.  Very excited about that.  Been looking on the net for suggestions.  Can't wait.

The house is full of kids. Again.  They come pretty much every day now.   I didn't have children my own age living close by when I was young, so I like that my kids do.  They're fighting with their lasers.  They make the exact same sound as in the Star Wars films.  Very annoying.

After many thoughts, I finally found the premise.  At least, I think I did.  I'm still not sure about it, but it seems right.  I had to rethink my story, the way I wanted to tell it, in order to find it.  The story will remain pretty much the same.  It will be a serie of 3 books. 

I looked on the internet for some clues and I got more confused than when I first started.  Some said that Harry Potter's premise is a school for witches and a world where muggles don't know about witches. So, two premises.  Which one is good.  Both, maybe.

So, my premise is:  even the most unlikely of legend can be true.  Does it make you want to read it?
