Radek, king of the Underworld, knows that Nia is destined to be his. Yet as the crown princess of Upperworld, Nia is unavailable to him. Desperate to claim her, Radek puts the safety of his own colony at risk and lures her to him by seducing her in his dreams. A progressive ruler, Nia believes in the importance of modernization. But as princess, her say is limited. Her mother, the Queen of the Upperworld, forbids the Underworld's king from attending Nia's crowning. So when a man from Underworld invades Nia's dreams and invites her below, she accepts the offer, hoping for an audience with the king. The moment Nia lands in Radek's throne room, she realizes her mistake. By Underworld law, she is Radek's slave for seven days—and seven nights. Radek vows to make use of every moment. Nia's society expects women to dominate in bed, but Radek draws out her hidden desires. How can serving him be so deeply thrilling? Even when he shows her the pleasure in pain, she craves more of his brand of dominance. Publisher's Note.
