Here's a few others :) Quite a few texting fics here xD.
The Prophet's Journal by petalsonparchment
Summary: Lily liked to believe (no, she insisted) that she could handle the visions. That if she just stayed calm and clever enough, she could outwit fate like it was an overdramatic entry in her diary, not a prophet's fable.
The trouble was, fate didn’t seem particularly interested in being rewritten.
-Hogwarts AU, Lily has visions of the future as she describes through her journal entries.
New Age Romancing by clarewithnoi
Summary: "Sirius: ok what’s this about u being in love
James: Padfoot she’s AMAZING
James: most beautiful girl I’ve ever seen in my life I swear
James: like she could kick me in the throat and I’d thank her tbh
Sirius: as would I
James: … rude??"
-Modern University AU Jily texting fic.
here's to never growing up by elixirsoflife
Summary: A group chat documents the lives of four highly dramatic teenage boys as they navigate their A Levels. Or, like, die trying.
- jily + wolfstar texting fic.
Meet Me At The River by charmsandtealeaves
Summary: A chance encounter with a misplaced owl leads to a correspondence between pen pals. Lily confides in her mysterious Flea and finds herself falling along the way.
-Hogwarts fic, also a one-shot.
haha, unless... by ohmygodshesinsane
Summary: Lily Evans is not a problem-causer, really, truly - she's just surrounded by them. How is she supposed to have a normal life when her roommates are completely barmy, her sister hates her (and is planning a wedding), and now some random blokes from Marlene's class are barging onto her sofa every week to interrupt a hitherto sacred space? It's not as if she wants James Potter to be attacked by chavs, become Jesus, buy her coffee, or listen to her ramble about Petunia. Mostly that's his fault. Really.
-Another Modern AU Jily Texting fic.
Welcome to Pettyville by womeninthesequel
Summary: When Lily Evans accidentally sends a text to the wrong number, she isn’t expecting to find the right person behind it. She can’t stop talking to Prongs. The only thing is, Prongs can’t stop talking about the girl in his class. What could go wrong, other than the number?
-Texting fic and some delightful secret identity shenanigans.
Summary: James poses as an advice charm in Lily’s diary. He’s really got to start thinking through his shenanigans.
-Mostly prose but the diary is also the centre of the fic so I thought I'd mention it. Hogwarts fic.
