Fictional Fans

Okay, if you were loading your phone up with offline copies of longfic (20,000-300,000 words) from A03 to keep as your stash of emergency re-reads, what would you pick? Any fandom, pairing, age, no shame or standards except 'it's a good thing to have on hand when you really need a longfic'.

I am trying to come up with a list, but it's all coming stuff I've re-read too often lately, so I need some new blood or old blood I've forgotten.

(I have Murderbot, Barrayar, T. Kingfisher and Young Wizards as my emergency profic longreads on there, but I want some fanfic to pad it out.)
