Married to the Viscount — Sabrina Jeffries

One kiss...

Abigail Mercer was breathless with anticipation at being reunited with Spencer Law, whom she met once and later married by proxy. But now the dashing Viscount Ravenswood denies all knowledge of their union! Far too many witnesses have made it impossible for the secretive Spencer to reject his "bride" without causing a scandal. So he has proposed a marriage in-name-only until they can locate his mysteriously absent younger brother -- who is responsible for everything! -- and untangle this messy affair.

Abigail is incensed, irate...and irresistibly attracted to this handsome, infuriating man who hides his smoldering passion behind a proper exterior. So the lady will agree to his terms on one condition: Spencer must seal their bargain with a kiss. But he finds that one deep, lingering, unforgettable kiss isn't nearly enough. And keeping his hands off his pretty wife is going to be much harder than he thought...
