During one long summer day at the Burrow, Ginny considers Harry, Tom, Percy and diabolical tables as she tries to decide whether or not to insist on coming Horcrux-hunting; Luna makes a surprising contribution. Essentially gen, though slight H/G-ness.
It was a simple idea, or so Luna thought; have a go at writing a piece of wizarding fiction, both to fill a gap in the market and to escape from the dismal world of Hogwarts in her sixth year. But she didn’t anticipate that it would bring her into a conflict with Hermione that threatens to shake the very foundations of what makes her Luna Lovegood.
It is the summer before sixth year. Dumbledore is making a record of his reasoning on the significance of Tom Riddle’s diary, and how Voldemort can be destroyed.
The truth is, she thinks, I'm very good at believing. It was a talent, after all... Seventh year; Ron talks, Luna listens. Vaguely linked to Shades of Purple.
'How did he get in?' When Sirius Black breaks into Hogwarts for the first time, the students are exiled to the Great Hall and purple sleeping bags. Amongst them Luna Lovegood, who is quickly formulating her own theories...
When Dementors board the Hogwarts Express, it's not only Harry that's affected. Ginny is forced to relive her worst memory of the 'memory' that possessed her. 'Missing scene' from PoA. (Edited version of 'Riddle'.)
