Captive ― The Forbidden Side of Nightshade

"The first adult novel set in the world of the New York Times bestselling Nightshade series, Captive delivers a steamy, forbidden romance between sworn enemies drawn together by an irrepressible desire. Twenty-five-year-old Tristan Doran enjoys a life of incredible power and privilege. As a direct descendant of the Keepers-witches who have embraced dark magic-he defers to no one but his overlord, Lord Bosque Mar. For most of his life, Tristan has been kept out of the centuries-old Witches War, his bloodline too valuable to risk in battle. But when a beautiful, young human Searcher named Sarah is captured and made a prisoner in his Irish castle, Tristan's infatuation with her flings him headlong into the fray. Captive and captor, unable to contain their longing, embark on a passionate, forbidden romance together-only to learn that their love is at the heart of a prophecy predicting the downfall of the Keepers' ages-old reign. Captive explores the darker side of the richly imagined Nightshade universe,a fantasy world of powerful dark witches, shape-shifting wolf warriors, and fascinating history. The first of three erotic novels, Captive delves deeply into the fiery, illicit romance of two young lovers whose very desires invite their doom"--
