Quick Fixes is a series of tales about Repairman Jack. If you've never read a Repairman Jack story you're in for a treat. Check out the whole Repairman Jack Series.
Repairman Jack is a true libertarian. He has no SSN or any other records. He exists in the cracks in the system and makes his living "fixing" things for people when the law is not an option. And Jack is very good at his work. Individual stories in this collection have been published in earlier anthologies, and some are excerpts from longer books. They're all worth a second read, in case you're not a Repairman Jack virgin. Very highly recommended.
