I get a lot of mail. Every now and then, though, I get an email that I can't handle, that is asking questions that are so deep and so profound about what it MEANS to live in a fallen world, that is written with such keen yet unpolished first-hand observations ... that I have no choice but to publish it.
Those emails are almost always by soldiers.
There's a long tradition of the soldier/writer, going back to Xenophon and the Anabasis (March of the Ten Thousand). Xenophon wrote his chronicle 2,500 years ago, and it's as fresh and as meaningful a book as any you will read today.
