The Home Club is exclusive and expensive, a place for celebrities other "cool" rich people to gather and relax, while having the staff cater to their every whim. Club owner Ned Groom and his brother Adam operate several resorts around the world, where the ultra rich can party without fear of the prying eyes of the press, or regular people. 

Now Ned Groom is opening his biggest Home Club ever: Island Home, an entire island off the coast of England accessible only by a narrow road at low tide, or private helicopter. The opening weekend begins, and the huge staff must be ready for the carefully-chosen members coming to launch this new Club. But not everyone will survive the weekend...

This was an exciting novel with several surprises. Almost all the characters were kind of terrible people, though; it was hard to find someone to root for.
