Night and Day, by Virginia Woolf

In this novel, Katherine Hilbery must decide whether to be engaged to poet William Rodney, or to have a relationship with Ralph Denham, whom she finds much more interesting. Also in this story is Mary Datchet, a friend of Katherine's who is involved in the Women's Rights movement. Katherine's mother is struggling to put together a book about her late father, a famous poet, with help from Katherine. This book was first published in 1919. It is by far one of the best stories I've ever read.
