There's a fine line between pain and pleasure.

When Andi wakes up in her best friend's twin brother's bed, her entire world is tilted. She's confused about her own actions, hating the smirk on his stunningly handsome face, and more importantly, she can't find her underwear anywhere.

Andi Matthews has never seen Kalen Dresher in a romantic light. She's known him for years and the thought has never crossed her mind. But after an unforgiving, eventful night alone with him, she can't seem to get him out of her mind.

And now, everything is different.

Andi wants nothing more than to forget that the night even happened but when Kalen won't stop pursuing her, wearing her purity ring around his neck, and tempting her with promising words; how can she say no?

Especially when he knows everything about her so when she gets a boyfriend, Kalen's eager to prove to Andi that this new guy won't be able to figure her out the way he has. Will their intimate night lead to more? Or will this be the beginning of a disaster?

And more importantly, will Andi be able to figure out the difference between what her head wants and what her heart craves?
