A great gift idea for your girlfriend who likes Kurt Vonnegut could be a complete collection of Kurt Vonnegut's books. This would allow her to have all of his works in one place and she can revisit her favorite novels by him whenever she wants. If she already has all of his books, you could get her an autographed copy of one of his books, a Vonnegut-themed mug or t-shirt, or tickets to see a play or stage adaptation based on one of his works.
Or you can get her a star map with the date when she was born.
