Frequency (planetary bodies, book five)

Book five in the Planetary Bodies series. Zev Vertinen has a problem. She lusts after the one man she can't have-her captain, Frederick Jannes. They have a past-ritualized and uniquely sexual-but for her to remain a pilot aboard the CMC Theseus, they can never touch each other again. Of course that doesn't stop Zev lurking to catch a glimpse of Jannes naked, or making him the star of every one of her fantasies. Then sheen engulfs the ship. And the rules that have dictated their lives are changed. Jannes has changed them. Now he will fulfill another ritual. Hunting her down and making her his. No matter the cost.
