It calls itself Murderbot, but only when no one can hear. It worries about the fragile human crew who've grown to trust it, but only where no one can see. It tells itself that they're only a professional obligation, but when they're captured and an old friend from the past requires urgent assistance, Murderbot must choose between inertia and drastic action. Drastic action it is, then.

The Witcher meets Naomi Novik in this fast-paced fantasy rooted in Slavic folklore, from an assured new voice in genre As a witch in the walled city of Chernograd, Kosara has plenty of practice taming rusalkas, fighting kikimoras, and brewing lycanthrope repellent. There’s only one monster Kosara can’t defeat: her ex the Zmey, known as the Tsar of Monsters. She’s defied him one too many times, and now he’s hunting her. Betrayed to him by someone close to her, Kosara’s only hope is to trade her shadow―the source of her powers―for illegal passage across the Wall to Belograd, where monsters can’t follow. Life in Belograd should be sweet, but Kosara soon develops a fast-acting version of the deadly wasting sickness that stalks shadowless witches―and only reclaiming her magic can cure her. To trace her shadow, she’ll have to team up with the suspiciously honorable detective investigating the death of the smuggler who brought her across the Wall. Even worse than working with the cops is that all the clues point in a single direction: one of the Zmey’s monsters has found a crack in the Wall, and Kosara’s magic is now in the Zmey’s hands. The clock is ticking, the hunt is on, and Kosara’s priorities should be clear―but is she the hunter or the hunted? And in a city where everyone is out for themselves, who can Kosara trust to assist her in outwitting the man―the Monster―she’s never been able to escape alone?

Murderbot wasn’t programmed to care. So, its decision to help the only human who ever showed it respect must be a system glitch, right? Having traveled the width of the galaxy to unearth details of its own murderous transgressions, as well as those of the GrayCris Corporation, Murderbot is heading home to help Dr. Mensah—its former owner (protector? friend?)—submit evidence that could prevent GrayCris from destroying more colonists in its never-ending quest for profit. But who’s going to believe a SecUnit gone rogue? And what will become of it when it’s caught?
