October 10, 1914

One of Queen Victoria's many grandchildren was Marie of Roumania, (October 29, 1875 to July 18, 1938). She was the Crown Princess of Roumania, for 20 years, as the wife of the heir apparent to the Roumanian throne and reigned as Queen from October 10, 1914 to  July 20, 1927.
The main job of queens is producing more royalty and this she did. She was prolific in other ways also, and wrote fiction as well as memoirs. I like this picture of her reading a book, for the glimpse it gives of royal Victorian taste:

Her life of as an author is not remembered as well as her beauty and regal life, so here's a list of some her books. I compiled it from Worldcat.org.

The dreamer of dreams
by Marie, Queen consort of Ferdinand I King of Romania (1915).  (Her royal title is effectively part of the book title in these cases, but I am including the author's name and title only rarely in this list).

The stealers of light : a legend (1916).

Roumania; yesterday and to-day (1918).

Portrait of Marie, Princess Ferdinand of Roumania
(1921).

The story of naughty Kildeen (1922?).

Ode to Roumania (1923).

Why?: a story of great longing (1923).

The lost princess; a fairy tale (1924).

Ilderim : a tale of light and shade (1925).

The country that I love: an exile's memories (1925).

The voice on the mountain : a story for those who understand (1926).

On tour with Queen Marie, by Constance Lily Rothschild Morris; Maria, queen consort of Ferdinand I king of Rumania (1927).

Crowned queens (1929).

The magic doll of Roumania : a wonder story in which East and West do meet, written for American children (1929).

The story of my life (1934). (There were three volumes in all, with this title, the last with a publication date of 1935).

Ordeal; the story of my life (1935).

Memoirs by Vera Pihatcheff; [and] Marie, Queen consort of Ferdinand I King of Romania
(1935).

Masks (1937).

We saved her second book to be mentioned at the conclusion. It was published in 1913, a children's book, as many of hers were: The Lily of Life . Below is an illustration (by Helen Stratton) from the book . Perhaps Marie's vision of the outside world was as crowded as her castle interiors.

This list is not complete. It is hard to believe that some titles are not duplicates. While I doubt she wrote all of the texts (and some citations have what may be co-authors, or translators) she may have written more of these books than we think. She was smart and had a strong will. She was quoted as praising the Ba'hai faith. I take this as evidence of her intelligence.
