Holy Fire — Bruce Sterling

Ninety-four-year-old Mia Ziemann enjoys all the benefits of the late 21st century. It is a world in which power is in the hands of wealthy senior citizens, who have access to the latest in life-extension technology. Mia seems to have it all. Until she comes to an awful revelation. Her long and cautious life has been entirely starved of passion and adventure. Now she has one chance to do it over. It will require a radical and painful experimental procedure that promises to make her young again. But in this time and place, youth never comes without a price. First she must escape her medical keepers and become a fugitive in an underground world Of outlaw anarchists. From there she will begin her desperate quest to erase her future and relive her past one step ahead of those who would rob her of a second life.
