Dodo Collections brings you another classic from Max Brand, ‘The Untamed.’ The mysterious Whistlin' Dan Barry rides a black stallion named Satan, followed by a wolf dog named Black Bart. Dan has his own problems, but they multiply when he encounters Jim Silent and his outlaw gang. Frederick Schiller Faust (1892-1944) was an American fiction author known primarily for his thoughtful and literary Westerns. Faust wrote mostly under pen names, and today he is primarily known by one, Max Brand. Others include George Owen Baxter, Martin Dexter, Evin Evans, David Manning, Peter Dawson, John Frederick, and Pete Morland. Faust was born in Seattle. He grew up in central California and later worked as a cowhand on one of the many ranches of the San Joaquin Valley. Faust attended the University of California, Berkeley, where he began to write frequently. During the 1910s, Faust started to sell stories to the many emerging pulp magazines of the era. In the 1920s, Faust wrote furiously in many genres, achieving success and fame, first in the pulps and later in the upscale "slick" magazines. His love for mythology was, however, a constant source of inspiration for his fiction and his classical and literary inclinations. The classical influences are particularly noticeable in his first novel The Untamed (1919), which was also made into a motion picture starring Tom Mix in 1920.

Dodo Collections brings you another classic from Rudyard Kipling, ‘Letters of Travel (1892-1913).’ ? Letters of Travel, 1892-1913, originally published in 1920, is a collection of articles on Japan, the United States, Canada and Egypt. ? Kipling's works of fiction include The Jungle Book (1894), Kim (1901), and many short stories, including "The Man Who Would Be King" (1888). His poems include "Mandalay" (1890), "Gunga Din" (1890), "The Gods of the Copybook Headings" (1919), "The White Man's Burden" (1899), and "If—" (1910). He is regarded as a major innovator in the art of the short story; his children's books are classics of children's literature; and one critic described his work as exhibiting "a versatile and luminous narrative gift". ? Kipling was one of the most popular writers in England, in both prose and verse, in the late 19th and early 20th centuries. Henry James said: "Kipling strikes me personally as the most complete man of genius (as distinct from fine intelligence) that I have ever known." In 1907, he was awarded the Nobel Prize in Literature, making him the first English-language writer to receive the prize, and its youngest recipient to date Among other honours, he was sounded out for the British Poet Laureateship and on several occasions for a knighthood, all of which he declined

Dodo Collections brings you another classic from H. Rider Haggard, ‘Cleopatra.’ ? The story is set in the Ptolemaic era of ancient Egyptian history and revolves around the survival of a dynasty bloodline protected by the Priesthood of Isis. The main character Harmachis (the living descendant of this bloodline) is charged by the Priesthood to overthrow the supposed impostor Cleopatra, drive out the Romans, and restore Egypt to its golden era. As is the case with the majority of Haggard's works, the story draws heavily upon adventure and exotic concepts. The story, told from the point of view of the Egyptian priest Harmachis, is recounted in biblical language, being in the form of papyrus scrolls found in a tomb. Haggard's portrait of Cleopatra is quite stunning, revealing her wit, her treachery, and her overwhelming presence. All of the characters are mixtures of good and evil, and evoke both sympathy and loathing. ? Sir Henry Rider Haggard was an English writer of adventure novels set in exotic locations, predominantly Africa, and the creator of the Lost World literary genre. His stories, situated at the lighter end of the scale of Victorian literature, continue to be popular and influential. He was also involved in agricultural reform and improvement in the British Empire.? His breakout novel was?King Solomon's Mines(1885), which was to be the first in a series telling of the multitudinous adventures of its protagonist, Allan Quatermain. Haggard was made a Knight Bachelor in 1912 and a Knight Commander of the Order of the British Empire in 1919. He stood unsuccessfully for Parliament as a Conservative candidate for the Eastern division of Norfolk in 1895. The locality of Rider, British Columbia, was named in his memory.

They have not seen her for an age, not even at her father's funeral. And the news she brings is not so pleasant as it seems that she too has been widowed, but already has another wealthy and prestigious husband in her sights, the highly respected Duke of Kernthorpe. The Duke, who is much older than Lais, has invited her to bring her mother to meet him, an invitation that Lais does not extend to young Mena, seeing how beautiful she has become. Mrs. Mansforde insists that Mena goes with her and then it is decided that she will pose as her mother's employed companion. Once at the Duke's Castle Mena goes for a walk in the garden and then sees a stallion and rider galloping towards her. The horse is clearly out of control and throws the rider so Mena rushes over to see if he has been hurt. He is a handsome young man and when he looks up at Mena he thinks, because she is so beautiful, that she must be a Greek Goddess.

At the Duke's Castle love is to take each of the three women, Mena, Lais and their mother, by surprise and brings them ultimate happiness in the form of entirely unexpected suitors. And it seems that Fate has brought them together at the magnificent but mysterious Kerne Castle.

He published his Dead Man's Rock (a romance in the vein of Stevenson's Treasure Island) in 1887, and he followed this up with Troy Town (1888) and The Splendid Spur (1889).

Play first published in 1732. According to Wikipedia: "Henry Fielding (22 April 1707 – 8 October 1754) was an English novelist and dramatist known for his rich earthy humour and satirical prowess, and as the author of the novel Tom Jones.

Dodo Collections brings you another classic from James Henry, ‘The Madonna of the Future.’ ? We had been talking about the masters who had achieved but a single masterpiece -- the artists and poets who but once in their lives had known the divine afflatus and touched the high level of perfection. Our host had been showing us a charming little cabinet picture by a painter whose name we had never heard, and who, after this single spasmodic bid for fame, had apparently relapsed into obscurity and mediocrity. There was some discussion as to the frequency of this phenomenon; during which, I observed, H------ sat silent, finishing his cigar with a meditative air, and looking at the picture which was being handed round the table. "I don't know how common a case it is," he said at last, "but I have seen it. I have known a poor fellow who painted his one masterpiece, and" -- he added with a smile -- "he didn't even paint that. He made his bid for fame and missed it." We all knew H------ for a clever man who had seen much of men and manners, and had a great stock of reminiscences. Someone immediately questioned him further, and while I was engrossed with the raptures of my neighbor over the little picture, he was induced to tell his tale. If I were to doubt whether it would bear repeating, I should only have to remember how that charming woman, our hostess, who had left the table, ventured back in rustling rose-color to pronounce our lingering a want of gallantry, and, finding us a listening circle, sank into her chair in spite of our cigars, and heard the story out so graciously that, when the catastrophe was reached, she glanced across at me and showed me a tear in each of her beautiful eyes. ? Henry James, OM, son of theologian Henry James Sr., brother of the philosopher and psychologist William James and diarist Alice James, was an American-born author, one of the founders and leaders of a school of realism in fiction. He spent much of his life in England and became a British subject shortly before his death. He is primarily known for a series of major novels in which he portrayed the encounter of America with Europe. His plots centered on personal relationships, the proper exercise of power in such relationships, and other moral questions. His method of writing from the point of view of a character within a tale allowed him to explore the phenomena of consciousness and perception, and his style in later works has been compared to impressionist painting.

Charles Dickens was an English writer and social critic. He created some of the world's best-known fictional characters and is regarded as the greatest novelist of the Victorian era. His works enjoyed unprecedented popularity during his lifetime, and by the twentieth century critics and scholars had recognised him as a literary genius.

Dodo Collections presents Amanda M Douglas’s ‘A Little Girl in Old Washington’. Presented as a fantastic edition with a fully interactive table of contents. Amanda Minnie Douglas was an American writer of adult and juvenile fiction. She was probably best remembered by young readers of her day for the Little Girl series published over the decades flanking the turn of the twentieth century. Her "A Little Girl" series was one of the first examples of historical fiction for girls, while her Helen Grant books fall into the "college girl" genre that became so popular at the turn of the 19th/20th centuries. Her Kathie's Stories series - the first that she published - is a fairly typical example of 19th-century didactic moralism. Douglas began by submitting short stories and poems to local publications. In time her stories appeared in editions of The New York Ledger, Saturday Evening Post and the Lady’s Friend Magazine. Her first novel, In Trust, was published in 1866 and sold some 20,000 copies. Learning from this first experience, Douglas made sure to retain the copyrights on all of her future works. She would go on to publish at least a novel a year until her retirement in 1913.
