The world of the future, which has survived a destructive invasion. A society in which hybrids of earthlings and aliens walk the streets, craftsmen breed biomechanical monsters, and a person’s place in society is determined by “social rating.” This is a story about a guy who did not want to end up at the very bottom. To do this, he goes to an underground tournament between tamers of laboratory-bred horrors. And also, about the consequences of his decision, and those who will have to sort them out.
