For years, I've been calling Alfred Bester's
The Stars My Destination/Tiger! Tiger!* "a forgotten cyberpunk classic from the '50s" and "more cyberpunk than cyberpunk".
I was even more correct than I thought: William Gibson, one of the progenitors of the Cyberpunk Movement,
has just cited it as one of his favorite novels, going so far as to say "I doubt I’d have written without having read it."
Hunt it down, people.
It's still high on my list for
Books That Oughta Be Movies.
*Tiger! Tiger! was the title of the first book publication, but it was originally serialized as the Stars My Destination, and, frankly, that's a far better title.
