I've never read anything by Pamela Freeman before, and I really love the world she's created here. And, after looking at her website, it seems that her Castings Trilogy books are set in the same world so I may have to give them a read as well.
The world she's created is large and filled with lots of different groups of people. The Travellers are still hated and despised by some of Acton's People, who invaded the Traveller's land to begin with. The land is split into domains which are ruled over by Warlords. The Gods speak to certain people and magic is widely known of. Stonecasting is a well used way to tell the future.
It's a very different world from which we live in and Pamela has written it well. The hatred felt from some of Acton's People toward the Travellers is well known by some, I'm sure. The characters are likeable, and there are loads of them to choose from as well, so many that I'd have trouble picking a favourite. Very well written and a really good read, I definitely recommend it.
