I'm hoping someone can help, hoping to tap into the vast data base of minds out there. I'm searching for any novels or short stories on the subject of racing in space. Like, spaceships designed to be race cars and zooming past planets, etc. I have 'Rocket Jockey' by Lester del Rey, but I think there was a book by Roger Zelazny, can't remember the title. Any book or story suggestions are appreciated!
