Basically my thoughts on what Harry's life would've looked like had James and Lilly survived that fateful Halloween night. Technically an AU, no slash, I think. I'm not good at summaries, but it's hopefully pretty good and you should give it a try.
Basically what I think would've happened if James and Lilly Potter didn't die on 31 October 1981. Posting is very sporadic, and some of the chapters are pretty long. (The Regulus Black in the description isn't the same one from the books)
