Is my story good so far? Please help me!?

Sorry hon but its not quite there yet. You're chapters for one are way too short. Most chapters are many pages long instead of a few paragraphs. Your writing isn't horrible, I'll give you that, but the story is very bland and cliche. Like someone said, its Twilight minus the vampires(i think...). Thirteen years old is also way too young to be "in love". If your characters must fall in love, make them older. 16, 17,18...something like that. I think you could go two ways in your writing "career" so to speak. You could write fanfictions for things like Twilight so you can exersize your writing, but don't have to make up a story plot, or you could make up some simple, short story plots. I don't think you're quite ready to write books yet, but keep working at it!
