Is there anyone here over the age of twelve?

From the choices of reading material, i can't much tell.
Anything "important" you might need to know about the last in the HP series of CHILDREN'S books can be found in its Wikipedia entry.

I leave it up to all the adults to Google it for themseleves.

I myself just got finished reading Angela's Ashes by Frank McCourt and Red Thunder by John Varley.

You know, books for adults.
