As I look back on what I just read, I'm a bit unsure of the details - the plot somewhat nebulous...
What I can tell you is that this reminded me a little of [b:Special Forces - Soldiers|7842653|Special Forces - Soldiers (Special Forces, #1)|Aleksandr Voinov|https://d.gr-assets.com/books/1268851627s/7842653.jpg|10939227], where the two MC's are seasoned, hardened military alpha men on opposite sides. They are sworn enemies in a war that has been going on for over 300 years. Despite the fact that they should hate each other, should have probably killed each other many times over - they keep coming back, keep hanging on to a "relationship" that has been brewing for the last 13 years!
This novella packs a punch with plenty of twists and turns, both politically and emotionally. These stoic soldiers have no room for feelings, let alone attachments. Do they dare? This definitely ends on a precipice… and I'm intrigued.
