The Colony Club by Shelley Noble

It’s 1902 and Florence “Daisy” Harriman, married to a rich banker, could have chosen to live solely as a Gilded Age socialite. However, while she is an accepted member of the New York and Newport ruling class, enjoying her privileges, she is also a social reformer and suffragist, and later a diplomatic envoy. At the time of this book, loosely based on history, she realizes that the ladies of her acquaintance need an elite club in Manhattan, just as their menfolk enjoy spending time at male bastions such as the Union Club or the Princeton Club.*
