The details are very vague in my mind but I'm looking for the name of a book I read probably 7-10 years ago. It is about a young man/teenager that lived in a technologically advanced society where everyone had telepathic or holographic animal familiars. His was a cat.
They all lived in a cave or mountain or somewhere that seemed very primitive relative to the level of technology they had attained. The culture is very controlled, and I think he rebels against this somehow. For some reason, the boy has to leave the city and is hunted. There is a female that he meets who leaves with him or that he meets after he has left.
