When I Read Cat's Cradle

I've just finished Kurt Vonnegut's novel, Cat's Cradle. I'm not going to write a review. I just want to write how I feel.
When I read the beginning, I was amused. As the story went, I became curious and surprised. When the story ended, I felt empty. I feel like, "So it ends? There are still more to tell."
Now I'm reading another book.
