by Kurt Vonnegut. I'd read this book back in the 80's in graduate school. I didn't remember much
from back then, except the compound "Ice-9" which is a central theme of the book.
This book has a very engaging plot line and an ending with a unique twist. Along with the author (the book is told in the first person), the main characters are the children of a prominent nuclear physicist who hold the last bit of their father's creativity.
After reading this book again, I remember why I read most of Vonnegut's books in graduate school. They are unique.
