    Just in time because human war created the galaxy's newest star and Venus was all that was left of humanity. The lessons of Earth weren't completely missed. Venus's domed cities (the land areas were considered too dangerous to settle) made plenty of war, but their warfare was limited, civilized, and conducted by professional mercenary companies. Cities who stepped outside of the rules of war could be quickly nuked — a strong incentive toward cooperation. Of course, even 'civilized' warfare is still warfare and mankind's efforts were largely squandered in an entire world that is overrun with mutating and dangerous descendants of the species brought in by Earth's terraformers.In two linked novellas, author David Drake explores the mercenaries who carry on the wars. In the first, Surface Action, Johnnie Gordon joins his mercenary-uncle Dan Cooke in an attempt to overcome a conspiracy of mercenary companies to preserve their way of life — by preventing Johnnie's father from bringing about a peaceful union of Venus domed cities. With only Dan's mercenary company to protect the young alliance and with multiple opponents lining up, Johnnie's mercenary experience seems doomed. And that's before Dan comes up with a crazy idea involving a cross-country cutting out operation.In The Jungle, two junior officers face their own failings after their boat is damaged. Each perceives the other as embodying all of the characteristics that they know they are missing themselves — and each uses the other's example for inspiration, subtly living up to the other's misconceptions. But survival is only a part of the requirement. Because the Venus domed cities have themselves reached a critical situation. Somehow, men must reclaim the land while they still have the chance.In Seas of Venus, David Drake sees the romance of war, but he doesn't let it seduce him. Even distant warfare conducted by professional mercenaries has its costs — including the creation of a self-perpetuating and self-dooming system. The first story, Surface Action, is straightforward, with a twist ending. The Jungle is a continual twist as Drake gives us a deeper insight into the characters and into the world and society which spawned them. The non-linear time flow is occasionally confusing, but the storytelling works.Seas of Venus, especially The Jungle, is military SF at its best. And Drake's story of a true-life voyage to the jungle of Belize is a nice bonus.

    A Plague of Demons: One man found out the secret behind the aliens who controlled the world, harvesting "dead" soldiers to fight wars on distant worlds-and only he could stop them, if he could keep from getting harvested himself. Thunderhead: An officer has manned an outpost on a lonely planet for years, watching for the alien enemy that may never come, forgotten by the bureaucracy which sent him there-and then the enemy came! Test to Destruction: Aliens are testing a human prisoner to determine how serious a foe the human race might be-and they have chosen the wrong man to Test to Destruction. And much more.

    Neal Anson Clemons, brilliant physicist and martial arts expert, was born at the very moment that men first landed on the moon, and his dream had always been to find a way to travel to the stars. And now he and his team have achieved a breakthrough, both in building a warp drive, and finding a new energy source powerful enough to make the drive more than an interesting theoretical concept. With the help of a beautiful Air Force Major and astronaut, Tabitha Ames, the US Government has funded the project, including assembly in orbit of the first faster-than-light probe. Unfortunately, forces working behind the scenes have much darker dreams, and they do not hesitate to blow up a space shuttle, attempt to kill Neal and Tabitha, and use the stolen warp technology to start what they expect to be a short victorious war with the United States. But Neal has ideas for using warp drive completely unsuspected by America's enemies, and repelling the all-out attack is only the beginning of a titanic struggle to reach the stars.

    The a body with two holes in its neck and no blood left turned up at his back door, and he found himself dealing with the kind of information that can get a man killed, or worse, much worse.Being chased by things out of myth and nightmare, Jason has only two weapons: his best friend, and his won quick wits.In a battle against darkness, the brightest weapon is the light of reason.

    The alien Arachnids were an enemy whose like no civilized race had ever confronted. Like some carnivorous cancer, the "Bugs" had overrun planet after planet . . . and they regarded any competing sentient species as only one more protein source. Defeat was not an option. . . . The Grand Alliance of Humans, Orions, Ophiuchi, and Gorm, united in desperate self-defense, have been driven to the wall. Billions of their civilians have been slaughtered. Their most powerful offensive operation has ended in shattering defeat and the deaths of their most experienced military commanders. Whatever they do, the Bugs just keep coming. But the warriors of the Grand Alliance know what stands behind them and they will surrender no more civilians to the oncoming juggernaut. They will die first-and they will also reactivate General Directive 18, however horrible it may be. Because when the only possible outcomes are victory or racial extermination, only one option is acceptable. The Shiva Option.And peace isn't always wonderful Once the enemy is defeated, the central governments of the Inner Worlds were anything but willing to relinguish their wartime powers. To insure that their grip on the reins of power remained firm, the bureaucrats are allowing the non-human beings of the Khanate in, while keeping the Fringe Worlds out, smugly confident that this will keep the colonial upstarts in their place. The Fringers have only one answer to that: Insurrection.

    Outnumbered and on the defensive, Earth made a desperate decision. It would attack the aliens not from space, but on the ground-with forces the Trofts did not even suspect. Thus were created the Cobras, a guerilla force whose weapons were surgically implanted, invisible to the unsuspecting eye, yet undeniably deadly. But power brings temptation . . . and not all the Cobras could be trusted to fight for Earth alone. Jonny Moreau would learn the uses-and abuses-of his special abilities, and what it truly meant to be a Cobra.

    Many have native microbes dangerous to the human immigrants. Others have diseases brought to them accidentally -- or on purpose -- by visiting ships. When millions of lives are threatened, it's a job for the Interstellar Medical Service, and a Med Ship is sent to solve the problem. Calhoun is the best the Med Service has, and hard experience has taught him that often the major obstacle to curing the sick is... the sick. And removing that kind of obstacle may take very strong medicine.This book is a compilation of four books released in the 1960's: The Mutant Weapon, Doctor to the Stars, S.O.S. from Three Worlds and This World is Taboo.3 • Med Ship Man • (1963)57 • Plague on Kryder II • (1964)121 • The Mutant Weapon • (1959)231 • Ribbon in the Sky • (1957)285 • Tallien Three (aka The Hate Disease) • (1963)351 • Quarantine World • (1966)425 • The Grandfathers' War • (1957)505 • Pariah Planet (aka This World is Taboo) • (1961)632 • Editors' Afterword by Eric Flint and Guy Gordon

    And in spite of their more advanced weapons, the Centrans weren't sure just who had conquered who.

    An alien migration fleet -- 14,000 starships strong -- searches the stars for a new home, its homeworld forever lost. When they finally find planets that can support them, all they have to do is eradicate the pesky human natives, a task they assume is easily within their powers. But Earth's Commonwealth of Worlds isn't about to give up so easily -- even if it has to create and train something it hasn't had for centuries: soldiers!

    Trigger Argee is a crack shot, with reflexes that make lightning look lethargic, and also a top agent of the galaxy's Federation of the Hub. Separately, they have been making life miserable for human criminals, unfriendly aliens, and nefarious members of all species. But when a danger to the entire Hub civilization brought these two together, the galaxy would never be the same!

    His mission: save, develop, and protect the group of Pak breeders sent out into space some two and a half million years before...Brennan was a Belter, the product of a fiercely independent, somewhat anarchic society living in, on, and around an outer asteroid belt. The Belters were rebels, one and all, and Brennan was a smuggler. The Belt worlds had been tracking the Pak ship for days -- Brennan figured to meet that ship first...He was never seen again -- at least not by those alive at the time.

    The planet attracted unwary travelers, hardened space-sailors, and merchant buccaneers -- a teeming, constantly shifting horde that provided a comfortable income for certain quick-witted fellows like Flinx and his pet flying snake Pip. With his odd talents, the pickings were easy enough so that Flinx did not have to be dishonest ... most of the time.In fact, it hardly seemed dishonest at all to steal a starmap from a dead body that didn't really need it anymore. But Flinx wasn't quite smart enough. He should have wondered why the body was dead in the first place...

    1 RefugeeCALIGULA OF THE STARSThough he was later accused of every crime and sexual perversion in the galaxy, Hope Hubris began as an innocent. Because he defended his older sister against the violent lusts of a wealthy scion, Hope and his peasant family were forced to flee Callisto, one of the moons of Jupiter. Pursued by the bloodthirsty scions across the airless desert, they barely escaped with their lives. The illegal space bubble was overcrowded with refugees, all hoping to reach Jupiter for asylum.But the space travelers had not reckoned on the terrible threat of high space-the pirates, barbaric men who rape, rob, and murder, with no thought but to satisfy their bestial appetites. It will take all Hope's ingenuity to survive, but the atrocities he witnesses will never die. There is only one way he can be rid of them . . . REVENGE

    A caste of scientists arose who knew how to repair and operate the ancient machines, but not how they worked, and worshipped at the altars of the atomic gods who were said to make the machines run. Society was a strange mix of the modern and the medieval, with armies riding on horseback into huge spaceships, then flying to human colonies on other planets to wage war with swords and arrows. Then came the mutant Clane, who would have been put to death for his deformities had he not been born into the ruling family. Though his body was twisted, his mind was brilliant, and he not only recovered the lost science behind the ancient machines, but found the truth behind the legends of civilisation's downfall. Alien invaders, not human war, had reduced humanity to barbarism as a prelude for a later return in force to colonize the Solar System. And that return would happen soon, unless Clane could find a way to stop it. . . . For the first time, the entire Clane saga, told in the two novels Empire of the Atom and The Wizard of Linn, is complete in one volume.Mission to the Stars, Van Vogt's sweeping novel of interstellar adventure, is also included, along with the two short novels in the Ezwal series, chronicling the struggle of one man to convince a feral but intelligent species to join with humanity in the battle against a mutual enemy, but first he must convince the lone Ezwal who is trapped with him in a deadly jungle to co-operate, or neither will survive.
