All Seated on the Ground - by Connie Willis
It's nearly Christmas and the aliens have landed. Far from being a menace, however, or bringing greetings from another planet, the aliens are just standing there and scowling, with a look of "utter, withering disapproval," much like Meg's Aunt Judith, as a group of researchers from scientists to linguists to clergymen, politicians and an aroma expert try, unsuccessfully, to communicate with the aliens.
The only thing that seems to get through to the Altairans, as the authorities in Denver, where the aliens have landed, have named them, is certain music, especially Christmas carols. Journalist Meg and seventh grade girls choir teacher, Mr. Ledbetter, believe they have nearly figured out a way to communicate with the aliens, if they can just work out the details before the alien ship takes off or the aliens kill everyone on earth.
I am a big fan of Connie Willis and I enjoy these novellas of hers. Of course I read mine from the library. It has a nice holiday feel and I enjoyed everything about it.
