I've had this bookmarked for ages, ever since Lee recced it, and I'm so glad I finally got a chance to read. What a marvelous portrait of Petunia -- nuanced, sympathetic and real. As one of your other commenters noted, I liked that this was more of a gen piece than a romance, and that most of the fic was about her own self-discovery before she discovered love with Percy.
I really enjoyed all your supporting characters as well!
