They've infiltrated homes in Hong Kong, shops in Vancouver, the streets of Sierra Leone. They're not pets, they're not robots: they're real people, completely anonymous, unknown, untraceable. The characters in Samanta Schweblin's wildly imaginative new novel reveal the beauty of connection between far-flung souls - but they also expose the ugly truth of our increasingly linked society. Longlisted for the International Booker Prize 2020.
