Elizabeth von Arnim 
The Enchanted April [EPUB ebook] 

The Enchanted April is a 1922 novel by British writer Elizabeth von Arnim. The work was inspired by a month-long holiday to the Italian Riviera, probably the most widely read (as an English and American best seller in 1923) and perhaps the lightest and most ebullient of her novels. Von Arnim wrote and set the book in the 15th century Castello Brown. Critic Terence de Vere White credited The Enchanted April with making the Italian resort of Portofino fashionable.
Elizabeth von Arnim (31 August 1866 – 9 February 1941), born Mary Annette Beauchamp, was an English novelist. Born in Australia, she married a German aristocrat, and her earliest works are set in Germany. Her first marriage made her Countess von Arnim-Schlagenthin and her second Elizabeth Russell, Countess Russell. After her first husband’s death, she had a three-year affair with the writer H. G. Wells, then later married Frank Russell, elder brother of the Nobel prize-winner and philosopher Bertrand Russell. She was a cousin of the New Zealand-born writer Katherine Mansfield. Though known in early life as May, her first book introduced her to readers as Elizabeth, which she eventually became friends and finally to family. Her writings are ascribed to Elizabeth von Arnim. She used the pseudonym Alice Cholmondeley for only one novel, Christine, published in 1917.
