A fast-paced tale of unrequited love in a dystopian world that's part The Matrix
, part Fritz Lang's Metropolis
So, why three stars? Shit, I have no frame of reference with which to properly assess whether or not this is successful M/M romance. I've never read anything in the genre before.
So, taken purely as an SF story, it works pretty well. However, there were many questions left unanswered, and I didn't quite buy the assassin's return. I'm also not a fan of epistolary storytelling, but the author does handle this better than most.
The writing was crisp and engaging. I would read another story in the author's Syntax universe.
