Taboo by Kathleen Lawless

Bridgeman had nothing better to do for the week than be auctioned off among a group of wealthy socialites, all of whom are no doubt as bored as he is.
Blindfolded, he is transported to the country home of to an aloof and repressed widow.
He’s her plaything for seven days— in any capacity she chooses.
When Fallon starts to paint him, the experience catches them both off guard.
Not only does her subject rekindle Fallon’s creativity and passion, his presence stirs up other, more primitive passions. Passions and fantasies which he is happy to indulge. Passions that refuse to subside with the final strokes of her brush or the final hours of their time together.
As each day ticks by, they both realize one week will never be enough. And theirs is a future than can never be.
