She accidentally killed her friend?! My fiction story! What do you think?

Havent you already posted this? Its a great story packed full of emotion and mystery. I would adapt afew things, such as the begining, i think if you made that whole paragraph about how it was as accsident, it wasnt your fault, etc, and then finish the paragraph with something like "But why Diana" obviously not that but somehting similar. I think if you changed some vocab and punctuality it would be vastly impoved but its still great at its current stage, keep on writing and you will get better, and as you get better self doubt begins to go.. =) You could use this as a foundation for a much larger novel if you wished, either way im sure itll turn out good. Good Luck.
