Arthur Cleveland Finch was an eminently practical man. Naturally he didn''t believe that the carnelian cube was a "dream-stone" with supernatural powers. But, of course, if he were going to wish himself into another world, he would choose one where everything was perfectly rational. Finch got his wish - with a bang! And he soon discovered that one man''s rationality can easily be another man''s nightmare. He awoke a poet in a strange place where status meant everything and a man could be tried for umpteen kinds of crimes for reciting a poem in public. So, being optimistic as well as practical, Finch tried again - and again. And the worlds kept getting wilder, more improbable, and funnier - but more dangerous, too. The question was, could Finch find Utopia¿ before losing his skin?

The gods of Poseidonis - or Atlantis - were powerful and real. Now they were determined to destroy the kingdom ruled by the father of Prince Vakar, the one man whose mind they could not read. The only way to save the kingdom was to discover that thing which the gods feared most. To find it, Prince Vakar set out across the largely unknown world where dangers multiplied with every league. There he found savage countries and strange people - the wild Amazons; a voluptuous, ensorcelled queen; a too-charming girl who was half-horse, half-woman; dangerous magicians who ruled hordes of headless slaves; and the Gorgons, who could paralyze their victims at a glance. Behind was his ambitious brother, determined that Vakar must fail. Even closer were unknown enemies set on his trail by the suspicious gods. And to add to his troubles, Vakar had no idea of what he sought!

Strom: Mercury How did Mercury get such an enormous iron core? Why is its tectonic framework so different from any other planet or satellite? What is its crystal composition? Why is the crust so depleted in iron when the interior is so rich in that element? What are the polar deposits? Where do the elements in the exosphere come from? Mercury is a planet shrouded in mystery. Only 45 percent of its surface has been seen in any detail, and that was from the Mariner 10 flyby in 1974. Yet what is known only makes the planet more fascinating. New Earth-based observations have shed light on surface and exosphere compositions, and re-evaluations of the Mariner 10 data, using modern image processing techniques, show evidence for volcanic flow fronts, pyroclastics and other volcanic phenomena not seen before. This ground-breaking book not only chronicles what has been discovered, but looks ahead to what has yet to emerge. An accompanying CD contains all the best Mariner 10 images, including the data for each image, photomosaics and maps.

Aquilonia, once the proudest land in all of Hyboria, has fallen under the tyrannical reign of a mad king. As his brutal insanity sweeps the land, only one man dares stand against him: Conan the barbarian. Conan becomes the leader of an army of rebels, brave warriors who thought their battles would be fought with spear and sword, axe and dagger. In this they were mistaken, for their greatest foe is not the army of Aquilonia, but the vile sorcerer Thulandra Thuu. Dark clouds loom ahead for the people of Aquilonia, and only Conan can save them.

This dark fantasy novel was serialized in 1939 but never before published in book form. It tells the Faust legend with a twist, set in Depression-era New York City.

The King had a good head on his shoulders -- for the moment, anyway. Everyone agreed that King Jorian of Xylar had been a good and just ruler. In fact, many also agreed that, in this case, it was a pity that the laws of Xylar decreed that each randomly chosen King must reign for only five years and then, after due pomp and ceremony, have his head cut off! Understandably, Jorian himself was wholeheartedly in agreement with the second sentiment, so with the help of a spell provided by the wizard Karadur, he escaped from the beheading ceremony with his head still on his shoulders. Unfortunately, his beloved wife, Queen Estrildis, was left behind, and getting her out of Xylar would be anything but simple -- particularly with the Royal Guard of Xylar hot on the trail of their fugitive monarch. With Karadur''s magic, Jorian might be able to pull off the rescue. But first, he would have to locate a trove of ancient spells, deal with an enemy wizard, steal an item from a 500-year-old (but still beautiful) princess who turns into a giant serpent at inopportune moments, repair the giant tower clocks of Iraz to fulfill a prophecy, break a pirate siege, and finally fly back to Xylar in an enchanted bathtub and whisk away his beloved Estrildis before the Royal Guard notices that their King (not to mention his head) has returned. Then things began to get complicated....

“Mr. de Camp has the trick of being able to show technology engaging in feats as full of derring-do as those of Hannibal’s army. History as it should be told.”—Isaac Asimov, The New York Times Book Review The Pyramids of Giza, the Parthenon of Greece, the Great Wall of China, the Colosseum of Rome.

Sprague de Camp delves into the heart of the mystery. He introduces us to the master builders who had the vision, the power, and the passion to reach for the clouds and touch the heavens.

Here is a fascinating study by L. Sprague de Camp of controversial and often little-known happenings in science and technology, with an emphasis on the wayward activities of those who dabble in fringe science. The Fringe of the Unknown is in three parts. The first, "Our Ingenious Forebears," examines some of the mysteries and oddities surrounding ancient technologies. Occultists and pseudoscientists often attribute extraordinary knowledge and wisdom to "the ancients," crediting them with inventions and discoveries that have generally been accepted as accomplishments of recent centuries. De Camp refutes some of these claims, but goes on to show that the ancients, starting from a much lower base of general knowledge, nevertheless achieved some remarkably ingenious results. In Part 2, "Beasts of Now and Then," the author explores a number of oddities and controversies in biology, such as the curious adventures and ramifications of the elephant family, the never-ending efforts to prove that monsters from former eras still roam the earth, the celebrated sighting of a sea serpent by H.M.S. Daedalus in the South Atlantic in 1848, and the many speculations about the great waves of extinction that have, from era to era, impoverished the earth''s faunas. In Part 3, "Scientists, Mad and Otherwise," de Camp tells of the behavior of some scientists, from the merely eccentric to the certifiably insane, and examines the differences between real science and pseudoscience. This wide-ranging work is a treasury of entertaining accounts of history and science.
