In this deliciously romantic tale, Ruth Owen programs a code for seduction, proving that, when opposites attract, smart is sexy.   Chris Sheffield's Casanova reputation is holding him back in the high-tech world. So he's determined to prove that even playboys have brains. All he needs is a groundbreaking product like the artificial intelligence system Einstein. Acquiring it comes with one major complication: the alluring genius behind the technology.   More comfortable at a keyboard than in the boardroom (or the bedroom), Melanie Rollins doesn't trust Chris Sheffield's motives. Or the heated promise in his eyes. But Chris wants that computer . . . and its creator. He needs Melanie to believe that their dreams are one and the same. And there's only so much temptation a woman can take before she abandons her science experiments for a lesson in sexual chemistry.   Includes a special message from the editor, as well as excerpts from other Loveswept titles.
