A Win-Win Proposition

Sebastian Case relies on his irreplaceable assistant for everything. But since arriving in Vegas for a conference, mousy Missy Ward has transformed herself. From ordinary to ravishing. From modest and reserved to bold and sensual. And Sebastian, who'd barely noticed she was a woman, finds himself dazzled by her allure.
Now she's quitting and Sebastian will do anything to keep her. Including accepting her outrageous bet. One spin of the roulette wheel—black and she'll stay…red and Sebastian owes her one night of passion. What can he lose, except maybe his heart?
