Maude Meagher (8 April 1895 – 1977) was a novelist, author of "Fantastic Traveller", the tale of a young man living in a world of his dreams.
 She was born in Boston, Massachusetts to Rev. H.A. Meagher and Anne Maude Tomlinson.
 She graduated from the University of California, Berkeley in 1917, where she met her lifelong friend Catherine Urner, and became a reporter for the "San Francisco Chronicle" in 1918.
 In 1919-1920, she worked as a foreign correspondent and an actress in England and Germany, and then traveled with her friend Catherine through France, Algeria and Italy.
 In 1925, she wrote the adventure novel "Copper Mountain: Adventurous Days Among the Eskimos" partly based on the books of Vilhjalmur Stefansson.
 In 1930 she published her novel, "White Jade", a historical novel about Yang Kuei-fei telling how Po Chu'i (Bo Juyi) came to write his famous poem "Everlasting Sorrow" about Yang.
 In 1934, she wrote "The Green Scamander," a novel about the Trojan War from the viewpoint of the Amazons.
 With her friend Carolyn Smiley, Meagher started publishing World Youth magazine.
 They ran the magazine out of an adobe house called "Casa Tierra" which they built and lived in.
 When it was completed in 1947, it was reportedly the largest secular adobe in North America.
 They wrote of their experience in a book entitled "How We Built An Adobe House For World Youth".

The Secret Lovers, published by E.P. Dutton in 1977, was the third of seven novels by the American novelist Charles McCarry to feature an American intelligence agent named Paul Christopher.
 It takes place in 1960 and '61, a year after the events in the first Christopher novel, "The Miernik Dossier", published in 1973, and three years before the beginning of "The Tears of Autumn", published in 1974, which was actually the second book McCarry wrote about Christopher.
 Later books by McCarry, ten in all as of 2013, expanded from focusing solely on Christopher into what might be considered a chronicle of the Christopher universe: two novels feature his cousins, the Hubbards, and in many of the Christopher novels his father, mother, one-time wife, and daughter play important and recurring roles.
 Also in this universe is a 1988 historical novel, "The Bride of the Wilderness", about Christopher's ancestors in 17th-century England, France, and Massachusetts.
 McCarry had been an undercover operative for the Central Intelligence Agency for nine years before turning to writing, and his books were hailed for their apparent authenticity and realistic depiction of tradecraft.
 "The Miernik Dossier" received excellent reviews, and instantly established McCarry's reputation as one of the foremost American novelists of espionage.
 Like all of McCarry's books, this one displays "an almost Jamesian awareness of [its] European locale, the special authenticity of a loving expatriate writing of an adopted foreign land."
Guiyeoni (born 1985) is the pen name of internet novelist Lee Yoon-sae.
 She first reached fame with her novels "He Was Cool" and "Romance of Their Own", which spawned commercially successful films of the same name, as with another book, A Wolf's Attraction.
 Since then, one of her other books, "Do Re Mi Fa So La Ti Do", has become a film starring Jang Keun-suk.
 A movie of "To My Boyfriend" is also in planning stages.
 Despite her commercial success, Guiyeoni has been criticized for her lack of literary perfection, overuse of emoticons, and unrealistic setting in her works.
 Besides the aforementioned novels, she has also written "Africa", "Five Stars", and written and illustrated a manhwa called "Syndrome".
Old Angel Midnight is a long narrative poem by American novelist and poet Jack Kerouac.
 It was culled from five notebooks spanning from 1956 to 1959, while Kerouac was fully absorbed by his studies of Buddhism and Buddhist philosophy.
 Kerouac initially experimented with Old Angel Midnight (then called "Lucien Midnight") in 1953 in his diary titled "1953.
 Notes again."
 In entries dated from November 20 to December 3, 1953, he made notes on "Lucien Midnight" which was to be originally conceptualized in what he called "book movie" form, when he closed his eyes and projected onto paper a cinematic sense of what he heard.
 A bookmovie, he explained in Some of the Dharma, is a "prose concentration camera-eye visions of a definite movie of the mind with fade-ins, pans, close-ups, and fade-outs."
 Kerouac's notes on Lucien Midnight were written while staying in the Lower East Side where he initially heard sounds coming through a tenement window from the wash court below.
 He then heard voices coming from kitchens of the other occupants in nearby apartment buildings and a man named Paddy arriving home drunk, and even a junky stirring in his bed.
 Kerouac conceptualized an idea of developing a work based on James Joyce’s experimental novel "Finnegans Wake" (not "Ulysses" as indicated by Ann Charters in her introduction to "Old Angel Midnight" for Grey Fox Press) where the “sounds of the universe” became the chief “plot” with all of its associated “neologisms, mental associations, puns and wordmixes” that stewed a plethora of languages and “nonlanguages.”
 Kerouac determinedly “scribbled out in a strictly intuitional discipline at breakneck speed” the fledgling prose that would finally comprise the finished book for City Lights's Pocket Poet series eight years later.
 Kerouac's one dogma was to compose Lucien Midnight strictly in pencil by candlelight.
 Lucien Midnight differs from his sketching method of writing because it is based upon an aural experience, and not visual.
 The bookmovie approach was abandoned in 1953 in favor of a different approach he had stylistically achieved by 1956.
Brian Francis Wynne Garfield (born January 26, 1939) is an American novelist and screenwriter.
