Summary: Language is no longer learned, it is streamed to neural implants regulated by lang-laws. Those who cannot afford monthly Language Streaming services are feral, living at the fringes of society. Big tech corporations control language, the world’s most valuable commodity. But when a massive cyberattack causes a global language outage, catastrophe looms. Europol detective Emyr Morgan is assigned to the case. Suspect number one is Professor Ebba Black, the last native speaker of language in the automated world, and leader of the Babel cyberterrorist organization. But Emyr soon learns that in a world of corporate power, where they who control language control everything, all is not as it seems. After all, if the mysterious Ebba Black is to blame, why is the Russian Federation being framed for an outage it claims to have no responsibility for? And why is Ebba now targeted for assassination? As he and Ebba collide, each with their divergent agendas and value systems, Emyr faces an existential dilemma between loyalty and betrayal, when everything he once believed in is called into question. To prevent the imminent collapse of civilization, and a deadly war between the great federations, he must figure out friend from foe, as his life may very well depend on it. And with the odds stacked against him, he must find a way to stop the Babel Apocalypse.

Summary: Nothing is new under another sun. Not even murder. This mission should be simple. Exoplanetary scout Leif Grettison and ace pilot Yang Yong are off to deliver a load of supplies and reinforcing settlers to a recently colonized planet. It’s as routine as a starflight can be. Famous last words. Something is wrong with the colonists. They are astonishingly ill-suited for the task of settling a new world. The planet, too, is a poor place to plant a town for humans. Even if everything goes right, the colony might not survive. Then one of the colonists is found dead. Murder is a possibility. Not long after, another one dies—and this time, it’s definitely murder. In a world with only two hundred people, there’s at least one killer. Meanwhile, the colony’s new leader has a plan—but Leif has doubts. Will this man save the settlement, or use his power to become a dictator? Leif and Yong’s mission is clear: they must leave the colony in shape to survive. Leif is a retired soldier, not a detective, and when it comes to investigating a crime, he doesn’t have a clue. Literally. Still, it falls to him to follow the evidence and find the killer. He also needs to deal with the leader and the leader’s plan. If Leif fails, the only mystery may be how long it will take for everyone to die.

Summary: RETURN TO THE MEAN STREETS OF AUTUMN Valerius Bakhoum is dead and buried. Too bad he’s still flat broke and behind on the rent. Unsure what to do with himself—and of who he is—Valerius resumes his career as a detective by taking up the oldest case in his files: where do the children go?

With nothing but time on his hands, Valerius dives in head-first to settle the question once and for all and runs smack into a more pressing mystery: who killed one of Valerius’ former lovers? And do they know Valerius is still alive? Stalk the shadows of Autumn’s hidden places by Valerius Bakhoum’s side as he shines a light on secrets both sacred and profane, ones with shockingly personal connections to who he was—and who he might become. New Life in Autumn is the sequel to the Manly Wade Wellman Award-winning A Fall in Autumn.

Summary: Returning to the frozen planet Aren died on was bound to have complications... Major Aren Dalsgaard's newest assignment is to investigate a series of murders on the frigid planet, Drass, where relations between the Treaty settlers and the indigenous inhabitants have taken a nasty turn. A linguist and trained xenologist, Major Dalsgaard should be the ideal Special Investigations Officer for this case, but Drass is where he died, over a hundred and twenty years ago. Sent by his family to the chigyel city, Nyachung finds himself confronted with a murder charge, racial prejudice, and a man who claims to be a hero from his grandmother’s generation. The man could be crazy or he could be lying to manipulate Nyachung, but the sincerity in those spring-green eyes disturbs him more than anything else he's encountered in the foreigners’ city. Evidence that makes no sense, mysterious boxes, and a suspicion that they can't trust anyone in the city drives the major and Nyachung together and out into the wilderness. No one's telling Major Dalsgaard everything, but every step leads him closer to a feeling of imminent catastrophe if he can't wrap this case up in time.
