Fic search! (Pleas help?)

[bluelinehvn]

I'm going to be very little help here, in what I'm looking for, but I'll do my best. I somehow managed to not save a link to an epically-long Draco/Neville fic that I remember very little about. I just remember its serious length, involving the developing relationship between the two, and that there is some type of cure or help for Neville's parents near the end (possibly as a surprise to Neville?) and he's able to re-connect with them. It's been bugging me for days and I'm searching everywhere, but I'm hoping maybe it sounds vaguely familiar to someone and they can recommend something here.

Any ideas would be greatly appreciated! :)
