From the title story´s fantastical inter-dimensional assassins to the steampunk dystopia of "Grey Rabbit, Crimson Mare, Coal Leopard" burrowing through the ruins of a civilisation destroyed by a plague, from Black Mirror-esque tales of blockchain cryptography ("Byzantine Empathy") and Internet trolling ("Thoughts and Prayers") to a three-story hard-SF arc about artificial intelligence and the singularity ("The Gods Will Not Be Chained", "The Gods Will Not Be Slain" and "The Gods Have Not Died In Vain"), here are 17 interlinking visions that explore what it is to be human, and what it is like to abandon or transcend that. This collection confirms Ken Liu, author of the astonishing and multi-award winning The Paper Menagerie and Other Stories, as one of speculative fiction´s greatest short story writers.
