"Faye goes to Bakken" would be a good story, lively anyway.
Dora sold one of her pieces, straight off for what, $2k? Faye clearly posesses a welding spread, and has a driving licence. I would have thought she would make a decent income as a jobbing welder, round the local exhaust shops, body shops, light engineering, plus pieces for sale when she has time....it would get her out of herself and give her some discipline.
+1 that Marten is no use to her at all.
.... picking up an earlier point, "Faye and May go welding" might work. Question - can AIs drive? Faye needs a minder but I couldn't see it being May, there needs to be some dynamic to drive the whole issue. I don't see why an AI wouldn't be a competent welder, there's bound to be an app for it. NDT is worth money, too.
