If you're open to sci-fi:

Nathan Lowell - Smuggler Series (3 books, starting with milk run) or Trader Series (first 6 books, starting with quarter share)

Smuggler has more.... Intrigue and whatnot. Trader is pretty straightforward and "feel good", iirc.

I would say read both series to those points before going further with the Seeker Series and later books. I forget where in the series but at some point the characters cross paths so having read both series before then helps it all fit together.
