Exploratory teams are accompanied by Company-supplied security androids, for their own safety.But in a society where contracts are awarded to the lowest bidder, safety isn’t a primary concern.On a distant planet, a team of scientists are conducting surface tests, shadowed by their Company-supplied ‘droid — a self-aware SecUnit that has hacked its own governor module, and refers to itself (though never out loud) as “Murderbot.” Scornful of humans, all it really wants is to be left alone long enough to figure out who it is.But when a neighboring mission goes dark, it's up to the scientists and their Murderbot to get to the truth.

    He didn't want to use the weapon, but feared he might anyhow. This was a justifiable assumption, for Caswell was a homicidal maniac.It was a gentle, misty spring day and the air held the smell of rain and blossoming-dogwood. Caswell gripped the revolver in his sweaty right hand and tried to think of a single valid reason why he should not kill a man named Magnessen, who, the other day, had commented on how well Caswell looked.What business was it of Magnessen's how he looked? Damned busybodies, always spoiling things for everybody....Caswell was a choleric little man with fierce red eyes, bulldog jowlsand ginger-red hair. He was the sort you would expect to find perchedon a detergent box, orating to a crowd of lunching businessmen andamused students, shouting, "Mars for the Martians, Venus for theVenusians!"But in truth, Caswell was uninterested in the deplorable social conditions of extraterrestrials. He was a jetbus conductor for the New York Rapid Transit Corporation. He minded his own business. And he was quite mad.Fortunately, he knew this at least part of the time, with at least half of his mind........

    She's a data analyst for the CIA during the day, and a suburban wife and mother on evenings and weekends. After a series of personal struggles and professional failures, Quinn hopes to find redemption in her newest assignment: a series of bizarre assassinations where victims are found with three-digit numbers tattooed, burned, or carved into their flesh. As Quinn pursues the killer across the globe -- always one body behind -- their lives become entangled in ways neither of them can predict.This novella by Christian Cantrell (about 13,000 words) takes place in a world bordering on unprecedented change: as oil-based economies shift to hydrogen, the majority of wealth is redistributed across the globe; as aging nuclear arsenals are replaced with even more menacing threats, terrorists try to seize opportunities to tip the balance of power; and as humans become increasingly dependent on machines, massive indexes of information accumulate which can reveal almost anything about anyone to those who know how to use them.THE EPOCH INDEX is a story about a world changing faster than humanity can adapt to it -- a world which may require us to redefine what it means to be a hero.

    Written with the biting wit and penetrating insight that are his trademarks, this new collection is exciting and essential reading.
