The High Season by Judy Blundell

No matter what the world throws her way, at least Ruthie Beamish has the house. Lovingly renovated, located by the sea in a quiet village two ferry rides from the glitzier Hamptons, the house is Ruthie’s nest egg–the retirement account shared with her ex-husband, Mike, and the college fund for their teenage daughter, Jem. The catch? To afford the house, Ruthie must let it go during the best part of the year.

It’s Memorial Day weekend and Ruthie has packed up their belongings for what Jem calls “the summer bummer” the family’s annual exodus to make way for renters. This year, the Hamptons set has arrived. Adeline Clay is elegant, connected, and accompanied by a “gorgeous satellite” stepson.

The widow of a blue-chip artist, in a world defined by luxury and ease, Adeline demonstrates an uncanny ability to help herself to Ruthie’s life. Is Adeline just being her fabulous self, or is she out to take what she wants?

When an eccentric billionaire, his wayward daughter, a coterie of social climbers, and Ruthie’s old flame are thrown into the mix, the entire town finds itself on the verge of tumultuous change. But as Ruthie loses her grasp on her job, her home, and her family, she discovers a new talent for pushing back. By the end of one unhinged, unforgettable summer, nothing will be the same–least of all Ruthie.
