This omnibus edition includes two books: Local Custom and Scout’s Progress. Local Custom follows the marriage of Er Thom yos’Galen and linguist Anne Davis. Scout’s Progress introduces Aelliana and Daav yos’Phelium.
Prequels are always fun. In this case, Pilot’s Choice takes a look at the parent’s of the main characters from Agent of Change and Carpe Diem.
Local Custom is a good place to start as Anne Davis acts as our stand in explorer the alien world of the almost human Liad. They may speak a language based on the same root, but the tree has split off in interesting differences.
Scout’s Progress plays with some of the darker aspects of Liaden society. The romanticism of clans aside, a society based on the negation of individual rights has its own issues.
While not quite as gripping as the main series, Pilot’s Choice is a good place to dive deeper into the Liaden universe.
