I do so wish that you would update this. *sighs in longing*

Combining the Spark and innate powerful magical ability? Oh, that's just plain evil... Are you sure that you aren't a Spark yourself?

I've marked this one to follow ...

This is an awesome beginning. I cannot wait to see what Harry does with his new-found spark!

Probably something small at the beginning.

After all, even if the Sparks manage unbelievable feats, they all need a good grounding in science before they truly start breaking laws of nature.

At this point of time, Harry is a kid whose knowledge is severely limited to what the schoolchildren know. Therefore, he's not very likely to build doomsday devices and so on. Also, as I consider Voldemort's Horcrux memory dump absorbing overdone, it will not be happening yet. Maybe later, when Harry is better at everything on his own merits.

That said, I do have a couple ideas as to what he might do...

I wasn't to sure on the first two chapters if It would be a story I would like but I'm glad I stuck with it because the third chapter makes me what to know what will happen next and hope you update soon with it. Thanks for sharing and I look forward to seeing where this goes.

I'm hoping I shall not disappoint.

Interesting, I'll be looking foward for more future chapters. Also thanks for answering my challenge!

Well, you do have interesting if somewhat overly detailed challenges.
I hope this story shall bring you some measure of joy.
