I’m struggling to consider this sci-fi because the Sci-fi elements simply did not matter. It’s a love story told through letters from two key agents (?) on opposite sides of a war. I think. There is not clarification of what rly their jobs are or what this war is. The correspondence is wonderful, earnest, and poetic. I enjoyed it, but creating an unexplained sci-fi world just to use as a setting for a letter exchange felt incredibly useless, albeit innocuous. It was such a short read that I think it’s worth a one time go but I wouldn’t read it again!
