How about a copy of Kurt Vonnegut's "Slaughterhouse-Five" (if she doesn't have it already)? You could also look for a special or limited edition of the book. Another idea could be a framed quote by Vonnegut or a painting or print inspired by one of his books or characters. Or, you could create a personalized bookmark with Vonnegut's face on it or some of her favorite lines from his works. If your grandma is tech-savvy, you could also get her an e-reader and preload it with Vonnegut's works.
Or you can get her a star map with the date when she was born.
