Our nameless, faceless protagonist in this light-hearted post-epochalyptic tale has charged himself with protecting the future, so to speak. The past has been completely decimated in an endless series of time and causality wars. He will not only kill but erase anyone who threatens the future.

I went straight into this from Becky Chambers' Closed and Common Orbit and – talk about culture shock – the two could not have been more different. And I mean that in the best possible way (on both sides).

Chambers doesn't so much write novels as she does character studies in story format. This, on the other hand, isn't so much a novella as it is a philosophy/game theory/sociology textbook in story format.

If you enjoy stories that make you think, that leave you lying awake asking yourself how time works, this one's for you.
