Better than the first, the second book's story seemed a little more focused and progressed well to an exciting and fascinating conclusion. The book would have been better with a few more revelations about the "Entire," although I could sense the author is setting us up for some "big reveals" in the next two books. The story was still a good one, with plenty of interesting conflicts, especially those dealing with what it means to be faithful to one's family, even when separated by great distances or lengths of time. I think that is going to be one of the central themese to this series.
I'm committed at this point. I'm definitely going to finish the series. In fact, after I finish Rough Stone Rolling (I'm trying to alternate fiction and non-fiction books as I read), I will move on to book three. The other fiction books in my "to read" stack are going to have to wait.
