When charming rake Tristan Barrett sweeps Lady Elizabeth off her feet, stealing both her heart and a kiss in a secluded garden, her brother challenges Tristan to a duel. The only way to save her brother and Tristan from harm--not to mention preserve her reputation--is to get married. But her father, the Duke of Pemberton, refuses to allow his daughter to marry anyone but a titled lord. The duke demands that Elizabeth marry Tristan's older brother, Richard, the Earl of Averston. Now Elizabeth must give up Tristan to marry a man who despises her, a man who loves another, a man she'll never love.

Richard fears Elizabeth is as untrustworthy as his mother, who ran off with another man. However, to protect his brother from a duel and their family name from further scandal, he agrees to the wedding, certain his new bride will betray him. Yet when Elizabeth turns his house upside down and worms her way into his reluctant heart, Richard suspects he can't live without his new countess. Will she stay with him or is it too little, too late?
