Why I am recommending this: I love the idea of Henry encountering some of the other main characters pre-series. While trying to cope with Abigail's departure, Henry treats the skinned knees of a clever, brave little girl he finds hiding from her brother in an alley. He calls her George, and though it's never stated, it's obvious who "George" is—or who she will be to him later on (and I really love that). This fic is a lovely bit of backstory for Henry, "George," and their future relationship, and also shows a great (though some of the circumstances were slightly jossed by canon) glimpse of Abigail's reasons for leaving.

In case you want to be spoiled on who "George" is:

It's Jo!
