The Four Swans is the striking sixth novel in Winston Graham's classic Poldark saga, the major TV series from Masterpiece on PBS.

Just when Ross Poldark, now something of a war hero, seems secure in his hard-won prosperity, he must confront a new dilemma: the sudden infatuation of a young naval officer with his wife Demelza.
And it soon becomes evident that Demelza is not the only woman close to him whose life is in turmoil. Ross's old love Elizabeth, her cousin Morwenna, and his friend's new wife Caroline have also become embroiled in their own personal conflicts in life and in love. It's a time of dramatic change for Poldark and Cornwall, and those who cope best will come out ahead.
Winston Graham's The Four Swans will sweep you into new territory, as the stakes for the Poldark and Warleggan clans intensify in shocking ways.
