Doctorow has created a fascinating society, where death has been "cured" (just make sure you have regular backups so you can be restored to a clone if anything happens!), the economy is based on the esteem of others (their money-equivalent is called "whuffie"), and things are run be adhocracies. Unfortunately, the characters and plot don't quite hold up to the promise of that amazing setup. Julius is a guy with multiple degrees, who's written symphonies, and died a few times - and usually goes back to Disney World to reboot himself; now he's living at Disney and working on a crowd-control thesis with potential application to the wider world, which is getting a bit crowded due to people not dying. While he's there, a conflict develops with how to renovate or redo the park, and Julius takes things a little bit personally and obsessively.
