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 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.

Dodo Collections brings you another classic from H. Rider Haggard, ‘The Ghost Kings.’ "The Zulus have a strange story of a white girl who in Dingaan's day was supposed to 'hold the spirit' of some legendary goddess of theirs who is also white. This girl, they say, was very beautiful and brave, and had great power in the land before the battle of the Blood River, which they fought with the emigrant Boers. Her title was Lady of the Zulus, or more shortly, Zoola, which means Heaven." This is her story.

Dodo Collections present Mark Twain’s ‘The Prince and the Pauper’. Presented as a fantastic edition with a fully interactive table of contents. The Prince and the Pauper?is a novel by American author?Mark Twain. It was first published in 1881 in Canada, before its 1882 publication in the United States. The novel represents Twain's first attempt at?historical fiction. Set in 1547, it tells the story of two young boys who are identical in appearance:?Tom Canty, a?pauper?who lives with his abusive father in Offal Court off?Pudding Lane?in?London, and?Prince Edward, son of?King Henry VIII. The Prince and the Pauper,?seemingly a simple novel, handles several divergent themes and ideas simultaneously. Foremost is the basic idea of the exchange of roles and lines between the prince and the pauper and the constant reference to their twin fates. Prior to meeting each other, both boys have dreams of living the life of the other.? The Prince and the Pauper?is Twain's most carefully plotted novel, but unlike Twain's greater novels (such as?Huck Finn?and?Tom Sawyer), where there is a great deal of character development, in this novel the characters are scarcely developed at all; instead, they are used largely as pawns to move the plot forward. Therefore, the main emphasis of the novel is not on character; it is on Twain's ingenious plot devices.?

Dodo Collections present H G Wells’s ‘The War of the Worlds’. Presented as a fantastic edition with a fully interactive table of contents. ? The War of the Worlds is a military science fiction novel by English author H. G. Wells. It first appeared in serialized form in 1897, published simultaneously in Pearson's Magazine in the UK and Cosmopolitan magazine in the US. The first appearance in book form was published in London in 1898. It is the first-person narrative of the adventures of an unnamed protagonist and his brother in Surrey and London as? Earth is invaded by Martians. Written between 1895 and 1897, it is one of the earliest stories that detail a conflict between mankind and an extraterrestrial race. The novel is one of the most commented-on works in the science fiction canon. ? The War of the Worlds has two parts, Book One: The Coming of the Martians and Book Two: The Earth under the Martians. The narrator, a philosophically-inclined author, struggles to return to his wife while seeing the Martians lay waste to southern England. Book One also imparts the experience of his brother, also unnamed, who describes events in the capital and escapes the Martians by boarding a ship near Tillingham, on the Essex coast. ? The plot has been related to invasion literature of the time. The novel has been variously interpreted as a commentary on evolutionary theory, British Imperialism, and generally Victorian superstitions, fears and prejudices. At the time of publication it was classified as a scientific romance, like his earlier novel The Time Machine. The War of the Worlds has been both popular (having never gone out of print) and influential, spawning half a dozen feature films, radio dramas, a record album, various comic book adaptations, a television series, and sequels or parallel stories by other authors. It has even influenced the work of scientists, notably Robert Hutchings Godd.

In "Marriage as a Trade" Hamilton asserts that "woman, as we know her to-day, is largely a manufactured product; that the particular qualities which are supposed to be inherent in her and characteristic of her sex are often enough nothing more than the characteristics of a repressed class and the entirely artificial result of her surroundings and training."

This tale of scientific rejuvenation was the number one best seller of 1923. The story centers on the relationship between thirty-four year old columnist Lee Clavering, and Mary Zattiany, a 58 year old woman who, through modern science, has regained her youth. The story takes place within New York’s high society and there is much criticism of both the older and younger generations in the 1920s. The older generation is argued to be unreasonably caught up in convention while the younger generation is shown as being too eager to flout their straying from those same conventions.

In the vaulted Gothic towers of Notre-Dame lives Quasimodo, the hunchbacked bellringer. Mocked and shunned for his appearance, he is pitied only by Esmerelda, a beautiful gypsy dancer to whom he becomes completely devoted. Esmerelda, however, has also attracted the attention of the sinister archdeacon Claude Frollo, and when she rejects his lecherous approaches, Frollo hatches a plot to destroy her that only Quasimodo can prevent. Victor Hugo's sensational, evocative novel brings life to the medieval Paris he loved, and mourns its passing in one of the greatest historical romances of the nineteenth century.

Dodo Collections brings you another classic from Max Brand, ‘Bull Hunter.’ Hunter was a man who could rip a tree trunk from the ground with his bare hands or tame the wildest stallion with his kind manner. Nobody west of the Pecos would have dared run afoul of the mighty frontiersman. But Pete Reeve didn't have the reputation of a dead shot because he relied on his common sense. Then Bull and Pete crossed paths, and townsfolk from Cheyenne to San Antonio braced for the battle.

Dodo Collections brings you another classic from Jacobs W.W, ‘Captains All and Others.’ ? William Wymark Jacobs was an English author of short stories and novels. Quite popular in his lifetime primarily for his amusing maritime tales of life along the London docks (many of them humorous as well as sardonic in tone). Today he is best known for a few short works of horror fiction. One being "The Monkey's Paw"(published 1902). It has in its own right become a well-known and widely anthologized classic. ? In 1879, Jacobs began work as a clerk in the civil service, in the Post Office Savings Bank, and by 1885 he had his first short story published. His road to success was relatively slow: Arnold Bennett writing in 1898 was astonished that Jacobs turned down the sum of ?500 for six short stories. Jacobs was financially secure enough to be able to leave the Post Office in 1899.

Can good and evil exist in one body? A London lawyer John Utterson investigates strange occurrences between his old friend Dr. Henry Jekyll and the evil Edward Hyde. The novella's impact is such that it has become a part of the language, with the very phrase Jekyll and Hyde coming to mean a person who is vastly different in moral character from one situation to the next or associated with a medical condition called split personality. The story may also serve as interpretation of a concept in Victorian culture, that of the inner conflict of humanity's sense of good and evil.
