Back in 1977, Ender's Game starts as a story in the magazine Analog -- revised and enlarged in 1985 as a book, and then in 1991 out came the "Author's Definitive Edition," which sounds to me like they stuck the introduction on the book.

In any case, this classic features a gifted class of children, with Ender Wiggin the most gifted, learning how to fight wars using wargames. The psychological implication about turning a child into a cold-blooded and aloof general is delightful, and the progress as Ender "graduates" to more complex games becomes a masterpiece of suspense.

Card's writing is quite pleasant and expressive. He builds up characters with flair and is particularly adept at making you root for this one or that one, and care what happens to major and minor protagonists and antagonists.

All told, Ender's Game comes well recommended.
