Tad and Hess

What kinds of challenges do you think Tad and Hess face moving from the colonies, where they were dealing with corrupt humans on NewEarth and corrupt smugglers from off planet in trade, to dealing with Heron, Grabon and the new territory? Mixing humans and dragon culture sounds complex… or at least it does to some people. They still plan to deal with offf world smugglers. If they continue with the market plan discussed in book 3 they would be dealing with human and dragon Craftsmen. Have they made their lives easier or harder? Why was their father so pleased?
