"When Ross Poldark plunges into a highly speculative mining venture, he risks not only his family's financial security but also his already-turbulent marriage. When his old flame Elizabeth Warleggan reenters his life, Ross is tested like never before. But soon, his wife, Demelza, retaliates, becoming dangerously involved with a handsome Scottish cavalry officer of her own. With the looming threat of bankruptcy and scandal, the Poldarks now face the possibility of disaster on all fronts. Will they be able to keep it together before everything falls apart? A tale of romance, revenge, and risk, Warleggan brings you characters and rivalries you won't soon forget"-- Provided by publisher.
