Context: Alexander "Alex" Shoumatoff (born November 4, 1946) is an American writer known for his literary journalism, nature and environmental writing, and books and magazine pieces about political and environmental situations and world affairs.  He was a staff writer at "The New Yorker" magazine from 1978 to 1987, a founding contributing editor of "Outside" magazine and "Condé Nast Traveler", and was the senior-most contributing editor to "Vanity Fair" since its re-inception in 1986 through 2015 before he pseudo retired.  He is known for reporting from the most remote corners of the world. Faith McNulty (November 28, 1918 – April 10, 2005) was an American non-fiction author, probably best known for her 1980 literary journalism genre book "The Burning Bed".  She is also known for her authorship of wildlife pieces and books, including children's books. Sonja Merljak Zdovc (born 26 October 1972, Koper) is a Slovenian journalist and author.  She is known for her columns and stories in the Slovenian newspaper "Delo", for her writings on literary journalism in Republic of Slovenia, her novels Dekle kot Tisa and Njeni tujci, as well as for her books on history of journalism in the Slovene Lands.  She is the editor-in-chief of Časoris, Slovenia's first online newspaper for children. The Santa Ana winds (strong, extremely dry down-slope winds that originate inland and affect coastal Southern California and northern Baja California), are commonly portrayed in fiction as being responsible for a tense, uneasy, wrathful mood among Angelenos.  Some of the more well-known literary references include the Philip Marlowe story "Red Wind" by Raymond Chandler, and Joan Didion's Slouching Towards Bethlehem. Joan Didion (born December 5, 1934) is an American author best known for her novels and her literary journalism.  Her novels and essays explore the disintegration of American morals and cultural chaos, where the overriding theme is individual and social fragmentation.  A sense of anxiety or dread permeates much of her work. Sándor Márai (originally "Sándor Károly Henrik Grosschmied de Mára", archaically English: Alexander Márai; 11 April 1900 – 21 February 1989) was a Hungarian writer and journalist. The culture of Hungary varies across Hungary, starting from the capital city of Budapest on the Danube, to the Great Plains bordering Ukraine.  Hungary has a rich folk crafts tradition, for example: embroidery, decorated pottery and carvings.  Hungarian music ranges from the rhapsodies of Franz Liszt and folk music to modern songs influenced by folk music and Roma music.  Hungary has a rich and colorful literature with many poets and writers although not many are known abroad due to the limited prevalence of the Hungarian language.  Some noted authors include Sándor Márai and Imre Kertész, who have been gaining acclaim in recent decades.  János Kodolányi was well known in Italy and Finland in the mid-20th century.  Imre Kertész won the Nobel Prize in Literature in 2002.  Péter Esterházy is popular in Austria and Germany, and Magda Szabó has recently become well known in Europe as well. The White Album is a 1979 book of essays by Joan Didion.  Like her previous book "Slouching Towards Bethlehem", "The White Album" is a collection of works previously published in magazines such as "Life" and "Esquire".  The subjects of the essays range widely and represent a mixture of memoir, criticism, and journalism, focusing on the history and politics of California in the late 1960s and early 70s.  With the publication of "The White Album", Didion had established herself as a prominent writer on Californian culture.  As one contemporary reviewer stated, "California belongs to Joan Didion." Hungarian literature is the body of written works primarily produced in Hungarian, and may also include works written in other languages (mostly Latin), either produced by Hungarians or having topics which are closely related to Hungarian culture.  While it was less known in the English-speaking world for centuries, Hungary's literature gained renown in the 19th and 20th centuries, thanks to a new wave of internationally accessible writers like Mór Jókai, Antal Szerb, Sándor Márai, Imre Kertész and Magda Szabó. Play It as It Lays is a 1970 novel by the American writer Joan Didion. " Time" magazine included the novel in its "TIME 100 Best English-language Novels from 1923 to 2005".
