Amagansett by Mark Mills
This complex first novel by screenwriter Mark Mills packs a lot in -- there's both a love story and a murder in its 400 pages. Amagansett gives an interesting depiction of the beginnings of changes in American society after World War II. Conflicts about race and class abound with rich descriptions of period detail. The book is also just a great read with a taut and suspenseful plot. A good choice for a book group.
