Thanks for adding "What goes around . . " to your library . . ."That day inDiagon Alley" is a one shot that should be read after chapter 5, I think - I tell you when at the end of the chapter - And "Having noth is a blessing " is the follow-up 7th year story.
I wrote "What goes around" before HBP came out, and finished "Having both before Dh, so if you see similarities, I did it first!! HA!HA!
ENJOY!
