Besides, he wanted her-in his bed, on the floor, against the wall, or anywhere else he could think of. Brianna had to choose-marry the captain or try to find another way to escape Bakom. Easy choice. Even though he was an alien, Char was the most desirable man she'd ever met. So, Brianna finds herself hurtling through space married to a very sexy alien-with a very flexible tail-from a planet where hedonism is the norm and there are three sexes: male, female, and hermaphrodite. But Bakom wanted Brianna too, and is willing to do anything to get her back.
