Meet Sirhan: Macx generation three, son of Amber-that-stayed, living on a floating city in the upper atmosphere of Saturn, arranging a family reunion - and to sue Amber-that-went for a couple of decades of maintenance.

Accelerando is a future history on a compressed timescale, in which earlier generations are still around to heckle their descendents. Nowhere is this clearer than in Curator. The whole story has a feel of taking stock; the fastest transition period is over, and we're in a fully-imagined future.

Each story looks backwards as well as forwards; history happens on the interface between old developments and new ideas. Sirhan himself is more interested in preservation than innovation. To survive, he proposes to sell history to the future; and in the process, he plans to create a family history.
"An old-fashioned book covering three generations living through interesting times," he suggests. "A work of postmodern history, the incoherent school at that - how do you document people who fork their identities at random, spend years dead before reappearing on stage, and have arguments with their own relativistically preserved other copy?
This is the start of the real meat of the book; the ideas dancing towards conclusion. Not just how can you record this type of world, but how can you live in it at all?
