I highly recommend reading either the short story or the book, “Ender’s Game.” The book is more detailed, of course, but they both tell the same story. The sequels are quite good, as well.
Orson Scott Card has interesting insights into politics, which are woven into those books. They are science fiction.
I read excerpts yesterday (and Card’s Introduction to his book...checked out his boyhood address in Orem, Utah) Interesting. Thanks.
