So far it's making for an interesting story.
I'm going to be a bit nit-picky here because I'm rather obsessive about proper english. At several points you go from past-tense to present-tense for a bit.
Overall, it's shaping up to be a good story. I can't wait to see what else you come up with. :)

Thank you
The tense changes are due to fluxes in the time/space continuum cause by Harry's dimensional transfer. Yeah, that's it. Fluxes. Yeah.
Thanks again.
