I like Ms. Roberson's style. Not too lush but not too spare either, she gives you plenty of concrete details to hang your imagination on. I liked this one enough to go read her other series and wait impatiently for her to finish this one. The only drawback is that it is clearly part of a long series and while you can pick up anywhere, you can't really walk away at the end of any one book and feel satisfied. Each generation overlaps the next and the past one, great for continuity, not so great for the wallet.
Note: It is best if the books are read in order, as the story can be confusing if you start reading in the middle.
