"She thought to quell me with her Scottish death glare. Hah!" God, I love your Minerva & her & Snape's long-term-firewhiskey-swilling-cigar-smoking-friendship . . .
Stunning, as always!
This is kind of like your very own crossover fic. As far as I can tell, you usually either write Snape/Harry learning to come to terms with life/their feelings about each other or DRACO/DRACO/DRACO (with a side order of Harry). But this time, we don't even have to choose, Harry gets to have gorgeous sex with Draco (though Draco doesn't swan as much as usual) AND fall in love with Snape.
This fic wraps up all the botched or unanswered questions about the best JKRowling characters in a way that's totally satisfying AND emotionally believable. Seeing Harry grow up/his children grow up, how Snape gets to have a friendship with A Lily (if not THE Lily) is so heartwarming.
Really, the only dangling question is: does Albus ever get a shot at Draco??
Oh, and I love what you do with all the painted worlds Snape gets to inhabit. Harry having himself painted in Snape's bedroom with a gigantic bed! And that ending is the best ever, Snape happy for the first time in his life/death, sliding into the beauty and heat that is Harry (GAH!)
