Oh my.  You're right, it's not a popular theory, but it does have merit.  (I hope you're wrong, and we'll find out soon!)

I really like how you've captured their dialogue, especially the bits of humor that keep it from being completely depressing.  Like, "but then, we didn’t try rodeo riding a giant snake through a house full of flying curses." *g*

And your last line is absolutely haunting.

Intensly written, but requires one crucial ingredient. It does not work for someone who does not believe that Harry is the last Horcrux (but cheers! to Ravenclaw's dagger!). I had to disagree with so many logical holes in your story that I had no time to actually enjoy the literary ride. This is a dispute fans cannot agree on since HBP and we won't solve it in this little review. Hence, sufice to say, I, personally, don't think so for the usual reasons.

So this is it. Three become two.

How utterly heartbreaking!!  I cannot imagine having to come face to face with such a harsh reality.  They are too young and have been through too much to have to experience this kind of tragedy.Excellent first time story!!

"He used Harry because the plan backfired. The protection that his mother placed on him was unexpected and fast. He was disembodied and had no way to take his planned Horcrux away from the scene. The intent to murder Harry had already split his soul that last time, so there were two pieces floating. He shoved one into the nearest thing that he knew would be protected. Harry.” Oh, this is so much better and more believable than the simplistic "oops!" theory we got from JKR. It makes far more sense to have Voldemort choose to make Harry the horcrux because he knows he will be protected to the ends of the earth by his arch-enemy, Dumbledore. It is spectacularly devious and evil and worthy of the master villian Voldemort is supposed to be. An excellent theory very emotionally portrayed. Thank you.

You wrote this with great plausibility and pathos.I've long thought it a probability, but I usually keep him a proto-Horcrux because I don't think Voldemort had the opportunity to seal the spell.  ::grins:: I'm always looking for a way out for poor Harry! 

Hiya. I just wanted to say that for your first fanfic, you did a great job. I think that the characters' actions are believable for the situation that they are in. You write well, so I hope to see more from you. That said, I truly don't believe Harry is a Horcrux after reviewing the info given to us by Dumbledore, but I can suspend my prejudices on that long enough to enjoy something well written.

I really disagree with your premise of this story, but you did a good job writing it.  Here's why I disagree with your premise:  You probably know that the Mugglenet book makes a claim that Harry is a Horcrux, but I think they're completely wrong as we know that the creation of a Horcrux requires that the one casting it must first kill someone and then take the split piece of soul, recite the incantation, and then bind the soul fragment to the selected "vessel" where it is supposed to remain.  I think that Voldemot intended to use the "special" killing of the baby Harry to be the death he used for creating the Horcrux.  So, since the curse backfired, he didn't have time to cast the spell.That said, it is certainly an interesting premise and you've done a lovely job with the dialog.  It really fits the characters quite well.  I'll be on the lookout for more of your stories.

Whee!  Here it is.

I love your interactions between the three of them - nice characterizations and good dialogue.  The humor is nicely woven into what would otherwise have been a very sad piece as well.

What ever happened to the locket? Although, placing a curse on the DADA position now makes a lot of sense - to hide the dagger hidden in the DADA office.
