Qualityland by Marc-Uwe Kling

In the near future sci-fi world of Qualityland, algorithms help create an idyllic life for its citizens, but what if the perfect world wasn't built for you?

Welcome to QualityLand, the best country on Earth. Here, a universal ranking system determines the social advantages and career opportunities of every member of society. An automated matchmaking service knows the best partners for everyone and helps with the break up when your ideal match (frequently) changes. And the foolproof algorithms of the biggest, most successful company in the world, TheShop, know what you want before you do and conveniently deliver to your doorstep before you even order it.

In QualityCity, Peter Jobless is a machine scrapper who can't quite bring himself to destroy the imperfect machines sent his way, and has become the unwitting leader of a band of robotic misfits hidden in his home and workplace. One day, Peter receives a product from TheShop that he absolutely, positively knows he does not want, and which he decides, at great personal cost, to return. The only problem: doing so means proving the perfect algorithm of TheShop wrong, calling into question the very foundations of QualityLand itself.
