Adrian Tchaikovsky's Service Model is a darkly comic sci-fi novel about a robot valet named Charles who wakes up one morning to discover he has murdered his owner. With no master to serve, Charles embarks on a picaresque journey through a post-human landscape, encountering other robots still faithfully executing their programming in a world where humans have largely disappeared. It's a sharp satire on servitude, purpose, and what happens when the systems we build outlive us. Tchaikovsky brings his signature wit and world-building prowess to a story that is equal parts Wodehouse and Asimov. If you've ever wondered what Jeeves would do after the apocalypse, this is your book.
