Two soldiers and an airman - German, American and English - are thrown together at the closing hours of World War One. Although an effective story for the younger end of the YA market, there were things that could have been explored more, and some parts skipped - there's a paragraph with one of the soldiers mothers that did nothing to move the story on, for instance.
I've read The Burning Shore by Wilbur Smith, where he spends a page describing how an airman in WW1 dressed, and the stresses they were under as well as the infantry - that could have been explored more, for instance.
Dowswell merges in a lot of little details that add to the sense of place; but because of his target audience, he skims a lot of the horror, something he does admit in his afterword.
The sense of the utter futility of it all comes across well though.
