Such a great premise! The world is ending in six months, infrastructure is falling apart, cops still have jobs. This is the story of one such cop, a newly-promoted detective who takes his job more seriously than you’d expect. The plot around this is also good and the writing, especially the possible-world “What would the US look like if everyone knew with certainty that the world was ending in six months” is great storytelling. The cop is a bit of an aspy type, very dogged, not particularly good at people skills but very good at being a cop. First of a trilogy.
