Uller Uprising by H. Beam Piper Uller Uprising

Uller Uprising is the story of a confrontation between a human overlord and alien servants, with an ironic twist at the end. Like most of Piper’s best work, Uller Uprising is modeled after an actual event in human history; in this case the Sepoy Mutiny (a Bengal uprising in British-held India brought about when rumors were spread to native soldiers that cartridges being issued by the British were coated with animal fat. The rebellion quickly spread throughout India and led to the massacre of the British Colony at Cawnpore.). Piper’s novel is not a mere retelling of the Indian Mutiny, but rather an analysis of an historical event applied to a similar situation in the far future.

Fenris isn't a hell planet, but it's nobody's bargain. With 2,000-hour days and an 8,000-hour year, it alternates blazing heat with killing cold. A planet like that tends to breed a special kind of person: tough enough to stay alive and smart enough to make the best of it. When that kind of person discovers he's being cheated of wealth he's risked his life for, that kind of planet is ripe for revolution. (Introduction from the Gutenberg text)

Book cover Temple Trouble

I'll bet you did not know that our little earth is not limited to the single time line on which we happen to exist. That's right; There are actually thousands, no many millions of parallel times, each existing alongside all the rest, using the same real estate, but following their own path. Some extremely primitive, some very advanced, but all blissfully unaware of the others. Of course this does not affect us at all, unless ... unless one of these time lines discovers the existence of the others and then a way to move easily back and forth from one to the other...

The joint Space Navy-Colonial Office expedition was looking for new planets suitable for colonization; they had been out, now, for four years, which was close to maximum for an exploring expedition. They had entered eleven systems, and made landings on eight planets. Three had been reasonably close to Terra-type but were all disqualified by terrible animals or warlike inhabitants...

The War of the Worlds by H. G. Wells The War of the Worlds

Extraterrestrial invasion, the earth taken over by omniscient intelligences from Mars, the whole of humanity under siege and a nameless narrator who seems to be the lone survivor of the complete devastation of human civilization – scenes from a Hollywood sci-fi blockbuster? Far from it! The War of the Worlds by HG Wells was written more than a century ago and went on to become an iconic work in the science fiction genre, spawning a whole new genre of literature featuring alien invaders. It was in fact the first book to present the idea of conflict between inhabitants of different planets...

The Island of Dr. Moreau by H. G. Wells The Island of Dr. Moreau

One of the first instances of science fiction, Wells’ classic tale published in 1986 examines various controversial philosophical issues active at the time of its publication, most notable being the implications of vivisection and degeneration. Narrated by its everyman protagonist Edward Prendick, the novel follows the events of his stay at a mysterious island, home to ghastly secrets, horrors, and incomprehensible experiences. Furthermore, the novel features innovative themes which have become iconic in the modern science fiction genre, including moral and ethical responsibility, evolution, and man’s interference with the course of nature...

The Time Machine by H. G. Wells The Time Machine

A science fiction novel first published in 1895, The Time Machine was the first depiction of time travel, and the reason Wells consequently coined the term “time machine” which is now universally recognized. Furthermore it is considered to be one of the precursors to the science fiction genre and the Dying Earth subgenre. An undeniable classic, the novel offers a gripping plot, speculation, and an innovative portrayal of man’s hopes, fears, and human nature in general. The tale opens with the introduction of an English scientist and inventor, simply referred to as the Time Traveler, who hosts a dinner party for a number of guests...

The First Men in the Moon by H. G. Wells The First Men in the Moon

Written nearly seven decades before Neil Armstrong's historic “Giant leap for Mankind” this book by one of the most influential sci-fi writers in English is an interesting read.

Businessman and budding playwright, John Bedford takes a sabbatical from his work and decides to write a play. He moves to a lonely cottage in Kent where he hopes to come up with a theatrical masterpiece...

The Sleeper Awakes by H. G. Wells The Sleeper Awakes

The novel focuses on an Englishman, who falls in a deep sleep lasting two centuries, and sees him wake up in an unrecognizable setting and extremely wealthy. An enthralling tale of dystopian society depicted through a colorful imagination, The Sleeper Awakes concentrates on topics including dystopia, political power, religion, plutocracy, and individual and social awakening...

A Story of the Stone Age by H. G. Wells A Story of the Stone Age

This story is of a time beyond the memory of man, before the beginning of history. . .

Anticipations by H. G. Wells Anticipations

Wells considered this book one of his most important, a natural follow-up to such works as his Man of the Year Million and The Time Machine. His goal was to get people to think and act in new ways. The book starts with a look at how humans get along socially and how they carry out their business ventures. It then discusses how these elements influence others, such as politics, the world of work, and education. H. G. tried to make clear how the current social order was disintegrating without preparing another to take its place. He then traced the roots of democracy, which in its present state he saw as unworkable. Instead, he proposed a new republic. He also critiqued modern warfare.

Book cover Essays on Work and Culture

The author investigates the world of work against a backdrop of culture. Each of the 25 essays focuses on one aspect of the topic. For example, the first essay, "Tool or Man?" looks at two views of man. One is that of strength as the provider of security. The other is that of aesthete, as an enthusiast of the arts or academics or religion. In our culture, provider of security is the winner every time. Man as a source of multiple talents cannot be allowed. As the author frames the argument, "Specialisation has been carried so far that it has become an organised tyranny...

Book cover The Misplaced Battleship

"It might seem a little careless to lose track of something as big as a battleship ... but interstellar space is on a different scale of magnitude. But a misplaced battleship—in the wrong hands!—can be most dangerous." The world class con man and thief known as the Stainless Steel Rat (diGriz) has another very big problem to solve and this science fiction novella by the great Harry Harrison will see if he can solve it and perhaps four or five more like it before this fascinating and funny tale is finished. 'Use a thief to catch a thief' sounds great but it sometimes has unexpected results.

Book cover The Repairman

This is a collection of 3 of Harry Harrison marvelous early stories that were published in Galaxy, Analog and Fantastic Universe. The Repairman (1958) is a straight fun SF story of a man getting a job done. It is most typical of his later style in series like the Stainless Steel Rat; Toy Shop (1962), a short piece exploring bureaucratic blindness and one ingenious way around it and The Velvet Glove (1956), my favorite for its writing style, fun perspective, sly social commentary on the scene in 1956 and just plain delightful imagination. And he manages to pack excitement and mystery in at the same time.

The World I Live In by Helen Keller is a collection of essays that poignantly tells of her impressions of the world, through her sense of touch, smell, her imagination and dreams. My hand is to me what your hearing and sight together are to you. In large measure we travel the same highways, read the same books, speak the same language, yet our experiences are different. All my comings and goings turn on the hand as on a pivot. It is the hand that binds me to the world of men and women. The hand is my feeler with which I reach through isolation and darkness and seize every pleasure, every activity that my fingers encounter...

Though I have included a few old puzzles that have interested the world for generations, where I felt that there was something new to be said about them, the problems are in the main original...
