Patchwork system: Trash to Greatness

It started out as any other day for Jace Thorn. A routine repair turned into a hair away from death, saved by a sarcastic system to repair everything. Not everything is repaired how it's expected though. A broken microwave turned into an EMP. Not to mention what happens to the streetlights. Can Jace come to terms with his new best friend? Or will the sarcasm get the last laugh and drive him to give up his golden finger?
