I LOVE IT!

I can see your theory being very close to what happens in book 7. I think Snape will play a big role and help Harry and you've tied it together so nicely!

I love Harry but I have always felt his is not Voldemort's equal in magic ability. Harry isn't as gifted and gets a lot of help from talented friends. We know Harry isn't a killer. He is not going to be able to defeat the greatest Dark Wizard of all time on pure luck only.

Your theory just makes soo much sense to me...everything in it! Bravo! I think I'm going to read it again!
