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.

Two of the most famous contributors to the Conan legend write the official novel of CONAN THE BARBARIAN, the seminal fantasy film by John Milius. In 1982, Robert E. Howard''s iconic literary antihero, CONAN, slashed his way from page to screen after a perilous decades-long journey. With its potent mix of epic vistas and bloody battles, CONAN THE BARBARIAN thrilled moviegoers around the world and launched the film career of Arnold Schwarzenegger. To mark the occasion, CONAN authors and editors L. Sprague de Camp and Lin Carter were tasked with translating the visions of filmmakers John Milius and Oliver Stone back to the printed page in this rollicking novelization of the original screenplay. Heroic Signatures is proud to bring this sublime work of sword and sorcery back into print!

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....
