" This series is starting to get a bit disappointing. In Heartfire, Calvin didn't quite make the waves that I hoped he would. Instead, Card produced another average book in the series that from start to finish makes little progress in the overall conflict. And the overall conflict seems mediocre at this point as well - the conflict is simply how Alvin will build the Crystal City someday. I understand that Card meant to write an American epic poem or something and that perhaps he succeeded. However, the flow of the story isn't much my style. I still plan to finish out the story, but I don't expect any surprises in the final two books. And at this point, I don't even expect the final book to ever be published... "
