Oh, this is fantastic. I love the way you've shown us these fragments of lives, of people doing their best with things about to come crashing down around them.
I also love the respect you give to each of the characters. They're all trying to do the right thing, and even when their values clash, you manage to show us both sides. I particularly liked the conversation between Molly and Gideon, and then the following one between Molly and Arthur. (And thank you, also, for showing us that, just because Molly has chosen to focus on motherhood for a moment, that doesn't have to define her).
Your Minerva and Arabella are adorable. :) I am so going to imagine them now, post-series, off eating raspberry spongecakes together. I also loved your snapshots of the Marauders, and the way you deftly characterised each of them in just a few words.
And how lovely to see Augusta taking the plunge here, as well. She's so often defined in terms of Frank, Alice and Neville, it's great to see her step into the limelight for a moment.
The ending sent a chill down my spine. This is a really great look at a variety of characters in times of stress - and also a poignant take on the pressure that war puts on relationships. Wonderful story!
