Never On Time

After making plans to meet up with a friend, Luna Lovegood oversleeps, and when she arrives at their meeting place, unexpectedly saves her friends’ older brother. R/LL. The incantation for the Bat-Bogey hex is credited to Nell (Steel Lily). (Note: Though I do ship D/G, I've gotten attracted by Neville/Ginny as being possible canon, and it is hinted at in the story.)
