So far the story is developing slowly!
A couple of quotes to give you the feel of the book:
“Sometimes you took over one of the guard posts, checked your watch an hour later, and found that 5 minutes had passed.”
“The army gave outposts pretty names like Basil, Crocus, Cypress and Red Pepper. This reflects a floral preoccupation in our military which in naming things generally avoids names like Hellfire and Apache...”
And explains the title: flowers is the army code name for wounded.
