Terminal Alliance


Jim C. Hines - 2017
    This would have worked out better for all involved if they hadn’t arrived after a mutated plague wiped out half the planet, turned the rest into shambling, near-unstoppable animals, and basically destroyed human civilization. You know—your standard apocalypse. The Krakau’s first impulse was to turn their ships around and go home. After all, it’s hard to establish diplomatic relations with mindless savages who eat your diplomats. Their second impulse was to try to fix us. A century later, human beings might not be what they once were, but at least they’re no longer trying to eat everyone. Mostly.Marion “Mops” Adamopoulos is surprisingly bright (for a human). As a Lieutenant on the Earth Mercenary Corps Ship Pufferfish, she’s in charge of the Shipboard Hygiene and Sanitation team. When a bioweapon attack by an alien race wipes out the Krakau command crew and reverts the rest of the humans to their feral state, only Mops and her team are left with their minds intact.Escaping the attacking aliens—not to mention her shambling crewmates—is only the beginning. Sure, Mops and her assortment of space janitors and plumbers can clean the ship, but flying the damn thing is another matter. As they struggle to keep the Pufferfish functioning and find a cure for their crew, they stumble onto a conspiracy that could threaten the entire alliance.A conspiracy born from the truth of what happened on Earth all those years ago…

For one thing, genetic errors have crept in with each generation.

At least that's what the murder of a North clone in the English city of Newcastle suggests to Detective Sidney Hurst. Sid is a solid investigator who'd like nothing better than to hand off this hot potato of a case. The way he figures it, whether he solves the crime or not, he'll make enough enemies to ruin his career. Yet Sid's case is about to take an unexpected turn: Because the circumstances of the murder bear an uncanny resemblance to a killing that took place years ago on the planet St. Libra, where a North clone and his entire household were slaughtered in cold blood.The convicted slayer, Angela Tramelo, has always claimed her innocence. And now it seems she may have been right. Because only the St. Libra killer could have committed the Newcastle crime. Problem is, Angela also claims that the murderer was an alien monster. Now Sid must navigate through a Byzantine minefield of competing interests within the police department and the world's political and economic elite...all the while hunting down a brutal killer poised to strike again. And on St. Libra, Angela, newly released from prison, joins a mission to hunt down the elusive alien, only to learn that the line between hunter and hunted is a thin one.
