Ashley's War by Gayle Tzemach Lemmon. It's about the spin-up of the Army's Cultural Support Teams (CSTs) in Afghanistan in mid-2011. The idea was to assign females to special operations units to help wrangle/glean tactical intel from women and children during operations. Overall the program was a success, however the book largely focuses on the first casualty, 1LT Ashley White-Strumpf. It has added significance for me, as I did a tiny bit of work with these soldiers that summer.
On the whole, I highly recommend the book. The author's description of special operations can be a little erroneous & clunky, but she captures the story effectively. Even though I knew how it would end, the last third was a little difficult to get through.
