From Open Culture:
Back in 1991, Bradley Denton published Buddy Holly is Alive and Well on Ganymede. The next year, it won the John W. Campbell Memorial Award for Best Science Fiction Novel.
Writes Cory Doctorow on BoingBoing, Buddy Holly is Alive and Well on Ganymede “is the
great American comic science fiction novel, a book about the quest to

hermetically sealed bubble on a distant, airless moon.”
Taking advantage of new innovations (new since 1991), Denton has made
the novel available for free download on his website, publishing it

license. You can access the text in four parts here: Part 1, Part 2, Part 3, Part 4....MORE
