One Soldier’s War in Chechnya by Arkady Babchenko
I bought this in a bookshop at Heathrow, just filling time really.
I enjoyed it, it’s well written, very very bleak and reminds me Tolstoy and Lermontov. I presume that it is authentic, it certainly could be.
I gave it to two of my sons to read and they also found it amazingly bleak but strangely captivating.
