For Lana Halstone, the fantasy becomes a reality the night she has one too many drinks while celebrating a long weekend at their family cabin with her half sister, Megan, and stumbles into the wrong bedroom.
Lana has had a crush on Danny since the night she was twelve when Danny kissed her on a dare at the party where Megan had dragged her instead of babysitting. Now that Lana is eighteen and about to go away to college, she is willing to take a risk in order to live her ultimate fantasy. The fact that Danny thinks he is with Megan, his ex-girlfriend, makes it too perfect to pass up.
What she doesn't realize is Danny knows he has the wrong sister in his bed, but she's exactly the one he desires. He is not only willing to play along but he's also determined to make it a night she won't soon forget. He can't get over the beautiful woman Lana has grown into and he'll do anything to prove that he's worthy of more than just one night. It's a steamy, hot roller coaster ride he can't resist.
