Everyone loves Brendan O’Brian.

He's a golden boy and a charmer. A Senate staffer with political ambitions...and a secret history of sharing Diana Cooper with his twin brother Ian.

Now Ian and Diana are getting married, while Brendan climbs the ladder.

It doesn't matter how hollow he feels. Or that he fills the emptiness with late nights at work. Or that women pass through his bed, yet he's lonely as hell.

What matters is that everyone loves Brendan...

Except for one person.

Sonia Jacobson, Diana's college roommate, treats Brendan like he's gum stuck to the bottom of her shoe. She calls him "the devil incarnate," turns prickly as a porcupine when he's around, and reacts with disgust to his entire existence.

So why can't Brendan stop thinking about her?

After the tension explodes one night, Sonia makes him a surprising offer.

She’ll do anything he wants – his deepest, most hidden fantasies.

For seven days, until Ian and Diana's wedding.

The rules? No lies. No strings. No feelings.

And no secrets coming to light.
