Demelza Carne, the impoverished miner’s daughter Ross Poldark rescued from a fairground rabble, is now his wife. But the events of these turbulent years test their marriage and their love.

Demelza’s efforts to adapt to the ways of the gentry - and her husband - bring her confusion and heartache, despite her joy in the birth of their first child. Ross begins a bitter struggle for the rights of the mining communities - and sows the seed of an enduring enmity with the powerful George Warleggan.
