After the success of her collection The Woman Who Thought She Was a Planet, Vandana Singh returns to the short story in Ambiguity Machines. Her deep humanism interplays with her scientific background in stories that consider and celebrate this world and others, with characters who try to make sense of the people they meet, what they see, and the challenges they face. An eleventh-century poet wakes to find he is an artificially intelligent companion on a starship. A woman of no account has the ability to look into the past. And in ‘Requiem,’ a major new novella, a woman goes to Alaska to try and make sense of her aunt’s disappearance. Examining the revolutionary potential of speculative fiction, Singh dives deep into the vast strangeness of the universe without and within to explore the ways in which we move through space and time: together, yet always apart.
