Charlotte Maynard rarely leaves her mother's home, the sprawling Connecticut lake house that belonged to her late stepfather, Whit Whitman, and the generations of Whitmans before him. While Charlotte and her sister, Sally, grew up at "Lakeside", their stepbrothers, Spin and Perry, were welcomed as weekend guests. Now the grown boys own the estate, which Joan occupies by their grace--and a provision in the family trust. When Spin, the youngest and favorite of all the children, brings his fiance home for the summer, the entire family is intrigued. The beautiful and accomplished Laurel Atwood breathes new life into this often comically rarefied world. But as the wedding draws near, and flaws surface in the family's polite veneer, an array of simmering resentments and unfortunate truths is exposed.
