Moonlight Rhapsody by Nancy J. Cohen

When an ion storm causes Rolf’s spacecraft to crash on the planet Souk, he is captured and thrown into a slave labor camp. A diplomat turned spy, he’s on a secret mission to contact the resistance. But his plans go awry when he catches the eye of the beautiful female overseer who fancies him for her personal attendant.

Ilyssa is excited to meet the new slave. With his piloting skills, he might be able to fly her off the planet. But first she must rescue her parents, who are being held hostage by Pasha Ruel. Ruel uses Ilyssa’s power of siren song to mindwash his enemies. Can she convince the new slave that she’s been forced into her role?

Rolf isn’t sure if he can believe her story, but he accepts Ilyssa’s offer of freedom. Together they flee Ruel’s camp and begin a cross-country trek. Their trip is fraught with perils, including their forbidden passion for each other. Ilyssa’s gift comes with a price, and to follow her heart means to lose her special talent. Can she love a man when it means sacrificing her dreams?
