To start with i didnt expect much from this story. Title seemed a bit like something someone young would have thought up to give there Harry a reason to beat people up and be ''cool''. I'm glad to be pleasantly surprised. Writing was very good and encouraged me to keep reading.
Tonks has always been my favorite character and i think you added her in a very good way in to the story and i hope to see more from her.
What happened to Hermione does sound believable if Harry wasnt around in the first year. Its going to be interesting to see what will happen now that he arrived at Hogwarts.
So very well done so far and i hope to see some more in the future.
