Metal Fatigue

This was a solid dystopian sci-fi that reminded me a lot of Isaac Asimov's Caves of Steel.
Set in the lat 21st century in an isolated (by choice and governmental procedure) city of Kennedy, the local law enforcement are stymied by two new criminals; a thief who is targeting data pools and an assassin targeting council member in favour of reassimilation with the ReUnited States of America (RUSA).
The city is falling apart because they have got to the point were they have recycled everything they can and without an injection of new resources they are starting to go backwards.
Can our hero, Phillip Roads, find the crooks before the RUSA military rolls into town and takes over...
