And the answer is...
Well done, Carole. And bonus points to Soraya for her restoration connections!
I can only think of letters.
The Chance and the Black - Alphard is reading a letter.
Distantly - Andromeda receives letters from her cousins
Hearts Desire - Minerva receives a letter telling her she has the job at Hogwarts,
Mrs Tenuous of Tenuous Town.
I see the theme of complicated marriage relationships.
Chance Dawson, Muggleborn, in a loveless marriage with Lucinda, a pureblood.
Andromeda, a pureblood, in a marriage with Ted, a Muggleborn, to the displeasure of her family.
Minerva's parents in a difficult marriage between a witch and a Muggle. Minerva, a witch, engaging and then disengaging with a Muggle, Dougal. Later Minerva, a half-blood, married Elphinstone Urquhart, a pureblood.
So we have 3 purebloods married to non-purebloods (maybe 4, if Minerva's mother was a pureblood).
I am going to go for ....
Each story concerns a prefect ... or pair of prefects
Over a Mug of Tea - Hermione
How to Wait - Hermione and Ron
Fools - percy and Penelope.
Each Author is named after a character or name from the series
Hi, there. The batteries in my cordless mouse died during the night, so I had to wait until the stores opened this morning to go online. But there is a luxury in sleeping in and not having to rush.
All three stories depict a bittersweet situation, in which people are wanting something they can't seem to have.
Percy speaks of wanting respect and recognition that always seem to elude him. He also wants Penelope, but as we know from canon, he ends up without her.
Harry as an old man reflects on his potentially romantic relationship with Hermione, which never had a chance to develop because of the circumstances that they all found themselves in during the years of the war.
Hermione and Ron face the heartbreak of wanting a baby which they can't seem to achieve.
All three stories include happy elements too, which is why I use the term "bittersweet".
Sorry about the second post, but the site is being dodgy and will not let me edit my post.
All three stories feature Hogwarts staff members: Teddy Lupin, Severus Snape, Albus Dumbledore.
Later edit: I'll bet you're right, Carole. It's not just food, but specifically chocolate. There are various foods mentioned in the stories, but only chocolate is common to all of them. A suitable challenge for the day after Hallowe'en, when we are all dealing with the leftover candy
This has been an interesting game. It has been quite a challenge to find commonalitites in the groups of three stories, because even when the answer was obvious, one had to search hard for other commonalities in order to get the participation points and bonus points. I am impressed by all the work that Julia must have done to find these sixty stories and arrange them in groups. Thanks, Julia!
Sweeties, yeah! (Sorry, my kids say this all the time)
Lemon Drops - Albus is in a sweet shop
Cherry and Chocolate - chocolate is a sweet
The History teacher - Mention of Chocolate frogs
Actually, they all mention chocolate, too.
Great comp, Jules!
