In this thrilling, action-packed fourth installment in the Planetside series from acclaimed science fiction author Michael Mammay, retired Colonel Carl Butler gears up for another military investigation, full of danger, corporate intrigue, and tech people would kill for—perfect for fans of John Scalzi and Craig Alanson.  Colonel Butler has paid his dues and just wants to enjoy his retirement on a remote planet. But the galaxy has had other plans.  He has been roped into searching for a politician’s missing son and an industry magnate’s missing daughter. He has been kidnapped, violated numerous laws, and caused the destruction of colonial facilities. He’s famous—or infamous, depending on who you ask—praised and reviled in equal measure across the galaxy for his exploits. And he is determined to never let the government drag him into another investigation. But when a runaway twelve-year-old girl whose father has gone missing asks him for help, well…it’s a lot harder to say no. The girl’s father, Jorge Ramiro, was supposed to have been on Taug, a moon orbiting the gas giant Ridia 5, working on a dig with a famous archaeologist. But now there’s no sign of him and no record of him being there. Mining operations on the moon are run by two different consortiums, Caliber and Omicron—both of which have tried to kill Butler in the past. Butler doesn’t believe in coincidence. Landing on Taug with his right-hand man Mac, computer genius Ganos, and an elite security squad, Butler soon finds that they’ve charged back into the crosshairs—because Ramiro is not the only who has disappeared, and the perpetual darkside of this moon is hiding more than the truth about a missing archeologist…

From eight hundred years in the future, a runcible gate is opened into the Polity and those coming through it have been sent specially to take the alien maker back to its home civilization in the Small Magellanic cloud. Once these refugees are safely through, the gate itself is rapidly shut downbecause something alien is pursuing them. The gate is then dumped into a nearby sun. From those refugees who get through, agent Cormac learns that the Maker civilization has been destroyed by pernicious virus known as the Jain technology. This, of course, raises questions: why was Dragon, a massive biocontruct of the Makers, really sent to the Polity; why did a Jain node suddenly end up in the hands of someone who could do the most damage with it? Meanwhile an entity called the Legate is distributing pernicious Jain nodes and a renegade attack ship, The King of Hearts, has encountered something very nasty outside the Polity itself.

In charge of an old cargo spaceship, the Old Captain Orbus flees a violent and sadistic past, but he doesn’t know that the lethal war drone, Sniper, is a stowaway, and that the past is rapidly catching up with him. His old enemy the Prador Vrell, mutated by the Spatterjay virus into something powerful and dangerous, has seized control of a Prador dreadnought, murdering its crew, and is now seeking to exact vengeance on those who tried to have him killed. Their courses inexorably converge in the Graveyard, the border realm lying between the Polity and the Prador Kingdom, a place filled with the ruins left by past genocides and interplanetary war. But this is the home of the Golgoloth, monster to a race of monsters, the place where a centuries-long cold war is being fought. Meanwhile, the terrifying Prador King is coming, prepared to do anything to ensure Vrell’s death and keep certain deadly secrets buried... and somewhere out there something that has annihilated civilizations is stirring from a slumber of five million years. The cold war is heating up, fast.

It is a tale of revolution, of the rebellion of a former penal colony on the Moon against its masters on the Earth. It is a tale of a culture whose family structures are based on the presence of two men for every woman, leading to novel forms of marriage and family. It is the story of the disparate people, a computer technician, a vigorous young female agitator, and an elderly academic who become the movement's leaders, and of Mike, the supercomputer whose sentience is known only to the revolt's inner circle, who for reasons of his own is committed to the revolution's ultimate success.

Before our history began, another now forgotten civilization thrived. The people who roamed Early Earth were much like us: curious, emotional, funny, ambitious, and vulnerable. In this series of illustrated and linked tales, Isabel Greenberg chronicles the explorations of a young man as he paddles from his home in the North Pole to the South Pole. There, he meets his true love, but their romance is ill-fated. Early Earth's unusual and finicky polarity means the lovers can never touch.As intricate and richly imagined as the work of Chris Ware, and leavened with a dry wit that rivals Kate Beaton's in Hark! A Vagrant, Isabel Greenberg's debut will be a welcome addition to the thriving graphic novel genre.
