A Summer Affair - Elin Hilderbrand

She's the perfect wife and mother--and he's the perfect temptation in this "perfect summer cocktail of sex, sun, and scandal" (Kirkus Reviews).

Claire has a problem with setting limits. All her life she has taken on every responsibility, assumed every burden, granted every request. Claire wants it all--and in the eyes of her friends, she has it: a devoted husband, four beautiful children, even a successful career as an artist. So when she agrees to chair the committe for Nantucket's social event of the year, she knows she can handle it. Claire can handle anything.
But when planning the gala propels her into the orbit of billionaire Lock Dixon, unexpected sparks begin to fly. Lock insists on working closely with Claire--often over a bottle of wine--and before long she can't ignore the subtle touches and lingering looks. To her surprise, she can't ignore how they make her feel, either. Claire finds the gala, her life, and herself spinning out of control.
A Summer Affair captures the love, loss, and limbo of an illicit romance and unchecked passion as it takes us on a brave and breathless journey into the heart of one modern woman.
