Hello Chris, Thank you for your service. Just wanted to comment that, after having read some books on the Iraq War, I really love your title. Sand Castle captures perfectly the ephemeralness ( a word? sure, why not) of what was attempted there - trying to build something that would last out of a material that's resistant. Bet you were happy no one else thought of using it for all those books on the war. Hope to learn more from future interviews. Thanks!
