A nice (and, in retrospect, fortuitous) find, a pleasure to read, ... featuring tight prose and an extremely compelling voice, ... it's a novella (or very short book) written for (much) younger readers that stood up nicely for this (not young at all) reader.
As a culture, we long have glorified war (and combat) and, having grown up in and having served in the military (and, frankly, been associated with the Army my entire life), I am intimately familiar with (and still highly conflicted about) my youthful obsession with, well, all of it, from the uniforms and the weapons to the comradery to the history (nay, lore) to the culture to the community to the training to ... yes ... whatever it is that persuades you that (for me, leading up to and, ultimately, at the age of 20) nothing is more important and meaningful than repeatedly stepping out the door of a perfectly good airplane and earning the shiny silver wings I wore proudly on my chest ... and yet ... and yet ... I'm now at an age when I look at so much of this differently, which, in part, was why the book - narrated by a fictional author of (basically) my current age ... resonated so deeply.
It's not a perfect analogy, but reading this reminded me (vividly) of Walter Dean Myers' two wonderful (children's' or) young adult books, Fallen Angels and Sunrise Over Fallujah, even though they couldn't be more different.
It's a gem of (as I understand it) young adult fiction (or, apparently, according to the Library of Congress category, juvenile fiction), and I'm somewhat intrigued that I'd never heard of (or come across) it previously, particularly, to the extent it was originally published in 1993, it was in print long before the years in which I was most familiar with Rylant's work ... or at least her then more popular stuff that we read to our (then) kids (or they read when they were early readers).
I'm pleased this came to attention, and I immensely pleased that I found and read it.
