2008 Hugo Award nominees :: novella
"The Fountain of Age", Nancy Kress
"Recovering Apollo 8", Kristine Kathryn Rusch
"Stars Seen Through Stone", Lucius Shepard
"All Seated on the Ground", Connie Willis
"Memorare", Gene Wolfe
Of this list, I've only read the Connie Willis novella. I thought "All Seated on the Ground" was entertaining but somewhat lightweight reading.
