This is at least the fifth installment in the leisurely chronology of the Poldarks and the Warleggans and a good many affiliated others in this part of Cornwall--now almost rounding the bend into the 19th century during the Napoleonic Wars with their attendant poverty and discontent. Personal estrangements, however, take precedence: the longstanding feud between Ross Poldark (hero of the series, really--his own man and not always his wife Demelza's) and forbidding George Warleggan who suspects Ross fathered his second son. He might have. Then there are the local elections with the old aristocrats unable to choose successors from their own class. And a miscellany of marriages made and dissolving, births, deaths, as more than the slag shifts levels in this coal-mining country. The reconciliation of Ross Poldark and Demelza concludes this part of the saga (too forbidding a word) which one reads, as always, with appreciable interest and pleasure.
