Brielle and the Alien Geek - Intergalactic Brides, #1

Brielle has waited faithfully for her fiancé to return from Terran Prime, only to discover she's been engaged to a lying, cheating bastard, who tosses her out on her rear the moment he's back on Earth. Not one to go down without a fight, Brielle will do anything to ensure her survival -- even sign up for a bride exchange on another world. Syl has lived his life in his lab, always preoccupied with his experiments.
But the moment he sees Brielle, he realizes that perhaps his life has been missing something after all. Wanting and having are two different things. What would an exotic-looking female like Brielle want with an alien geek like him?
