Here's the copy from the original dust jacket:
It is an April day in the year 2000 and an era is about to end - those booming times of market optimism when the culture boiled with money and corporations seemed more vital and influential than governments.
Eric Packer, a billionaire asset manager at age twenty-eight, emerges from his penthouse triplex and settles into his lavishly customized white stretch limousine. On this day he is a man with two missions: to pursue a cataclysmic bet against the yen and to get a haircut across town.
His journey to the barbershop is a contemporary odyssey, funny and fast-moving. Stalled in traffic by a presidential motorcade, a music idol's funeral and a violent political demonstration, Eric receives a string of visitors - his experts on security, technology, currency, finance, and theory. Sometimes he leaves the car for sexual encounters and sometimes he doesn't have to.
Cosmopolis, DeLillo's thirteenth novel, is both intimate and global, a vivid and moving account of a spectacular downfall.
