High-Rise by J.D. Ballard

Within the concealing walls of an elegant forty-storey tower block, the affluent tenants are hell-bent on an orgy of destruction. Cocktail parties degenerate into marauding attacks on 'enemy' floors and the once-luxurious amenities become an arena for riots and technological mayhem.

In this visionary tale of urban disillusionment society slips into a violent reverse as the isolated inhabitants of the high-rise, driven by primal urges, create a dystopian world ruled by the laws of the jungle.
