Sister's Keeper. Best Friends, #1

Kelly's always considered herself the responsible sister. So when her twin abruptly elopes with a former boyfriend, she feels compelled to break the news to the man expecting to spend a romantic weekend with Karen. Her plans to do the right thing go awry when he mistakes her for Karen. One explosive kiss and she's helpless to stop herself from falling for Karen's jilted lover. Despite the desire raging between them, a part of her wants to confess her true identity.
A stronger, more sensual part, urges her to cast off her good-girl persona and revel in the knowledge that the man of her dreams can't keep his hands or lips off her. Dom Evans, just out of a bad relationship, is stunned when he opens the door one night to find himself staring at a shy, but sexy woman he can't resist. Although he knows she's playing a game of pretend, he wonders how long it will be before she realizes he's playing along.
