Flatland

By Edwin Abbott

On Sale $

$2.99

In Flatland, the more sides a man has, the more powerful he is. Triangles are laborers and soldiers. Squares and pentagons are middle-class doctors and lawyers. Hexagons are nobility. Women, however, are straight lines, incapable of advancement in a two-dimensional world. Everything in Flatland is clear-cut and orderly, until the day an average citizen—a Square—dreams of a land of three dimensions. If three dimensions are possible, why not four? Or one? Soon, the Square’s provocative imagination and corresponding adventures threaten to turn the whole of Flatland against him.

First published in 1884, two decades before Einstein’s theory of relativity defined time as the fourth dimension, Edwin Abbott’s Flatland is both a prescient exploration of the unseen and a delightful skewering of Victorian social strictures.

A battle for survival begins and ends in the human mind in the thrilling novel from the Time Traders series.

The latest gambit by the Western powers to outmaneuver the Russians was Operation Cochise—which launched Travis Fox and his crew on a ship bound for the planet Topaz. At least that’s what Fox thinks . . .

All he knows for sure is that something went wrong and they crash landed. Everything else is a fog of warped memories. When they come across a band of Russians who have also had their memories obliterated, Fox begins to suspect they are all pawns in a much larger game. And his speculations are right.

Someone is manipulating them. Observing them. And if Fox and his newfound allies cannot find a way to break free from their mental bonds, their captors may never be stopped.

The groundbreaking novella that gave rise to science fiction’s original space hero, Buck Rogers.

In 1927, World War I veteran Anthony Rogers is working for the American Radioactive Gas Corporation investigating strange phenomena in an abandoned coal mine when suddenly there’s a cave-in. Trapped in the mine and surrounded by radioactive gas, Rogers falls into a state of suspended animation . . . for nearly five hundred years.

Waking in the year 2419, he first saves the beautiful Wilma Deering from attack and then discovers what has befallen his country: The United States has descended into chaos after Asian powers conquered the world with advanced weaponry centuries before. All that’s left are ragtag gangs battling for survival against their brutal overlords.

But when Rogers shows them how to band together and fight for more than mere survival, he sparks a revolution that will decide the fate of the future world.
