The Angry Tide is the seventh novel in Winston Graham's classic Poldark saga, the major TV series from Masterpiece on PBS. Cornwall, towards the end of the 18th century. Ross Poldark sits for the borough of Truro as Member of Parliament - his time divided between London and Cornwall, his heart divided about his wife, Demelza. His old feud with George Warleggan still flares - as does the illicit love between Morwenna and Drake, Demelza's brother. Before the new century dawns, George and Ross will be drawn together by a loss greater than their rivalry - and Morwenna and Drake by a tragedy that brings them hope . And with the new century, comes much change in the shocking seventh book of Winston Graham's Poldark series, The Angry Tide. The Angry Tide will be part of season 4 of Masterpiece's Poldark TV series, which is scheduled to air in Fall 2018.
