Henry and June: From a Journal of Love: The Unexpurgated Diary of Anaïs Nin, 1931-1932 by Anais Nin, is the journal of famed American writer Anais Nin.

The book had been published previously but had been edited for content. This version of the book is comprised of 274 pages, spanning October 1931 - October 1932. There are no chapters. The sections are only divided by month.

Anais Nin (1903-1977) was an American diarist and author. Nin was best known as a diarist, although there were other works to her credit, including critical analyses and fiction. Nin's journals broke many barriers regarding women and sexuality. Nin was half Spanish (Cuban) and half French but raised in the United States. After Nin's marriage to Hugo Guiler, a banker who later became a filmmaker, the couple moved to Louveciennes in Paris. At the time of the writing, Nin and Guiler had been married for seven years.

Nin had been sick as a child. Nin's physical frailty and desire to please a father that did not want her set the author up to always seek out the approval of men who were similar to her father. This is, in part, what she found in Henry Miller.

Throughout the course of Nin's affair with Miller and others, the author discovered many things about herself, from her desire to submit to a need to explore many things which had been buried, if they had even existed before that time. Nin also engaged in psychoanalysis to discover her true self.

Nin stayed married to Hugo throughout the tumultuous years in Paris when Nin was with Miller and various other men, as well as Miller's wife, June, and other women. The openness of Nin's sexuality allowed her to be freer with herself than she ever had been while experiencing torment and obsession.

The book begins at Louveciennes, the western Paris neighborhood in which Nin and her husband, Hugo Guiler, have taken a home. The first entry details a visit by Eduardo, Nin's cousin and supposed first love.

Because the book is Nin's journal, the events are chronological. There is a clever use of flashback via Nin's mention of previous entries and former relationships. The background is also given through some of the discussions with Miller and Dr. Allendy.

While the journal deals with Nin's burgeoning sexuality and feelings about the main players in the book, i.e., Hugo, Miller, Eduardo, Mansfield, Erskine, and others, the main focus is on specific events that occurred, mainly between Nin and Miller. Also because it is a journal, there are some statements and references that are not entirely clear on their own and the reader is left to guess at their meaning.

Overall, Nin completely captures the year during which she had affairs with Henry and June. At the end of that year, Nin found herself entering into a new phase, perhaps one in which Miller and Mansfield would no longer be an obsession.
