'nother new one. The list is
here.
Okay - so not really a book. But a very good Fanfic which fits in (so far as I remember) with HP7. Not a HP story, technically, as it focuses on those who were left at Hogwarts. But very true to the feel of kids having to grow up suddenly, to the point where someone gives his own life for his wife & child.
No idea what'll be next - depends what new books are dug out of the boxes next...
