So we continue with the same theme from Monkey Suit, in that we’re on an lighthugger running away from Yellowstone and the Melding Plague.
This enjoyable little short introduces us to the real science of time dilation, wherein the nearer one gets to the speed of light, the faster time passes in the outside universe in relation to those on the space ship.
And if we take this idea and put those on the space ship in reefer-sleep, where their bodies and brains are taken down into hibernation state — so hardly ageing at all — and then send them close to light speed for a few years, decades can pass in the outside universe while these people age a few weeks or months: thus being known as dilation sleep.
Then if we look at the situation that is occurring on Yellowstone and consider that rich refugees can afford to pay Ultras to go on a trip around the galaxy in dilation sleep for a few years while hopefully everything back home gets sorted out, and that is where we are in this book.
Except that one of the crew has been awakened by the ship because something has gone wrong and needs fixing.
Good stuff.
Available in the collection, Galactic North.
And the next book in the Revelation Space series is Chasm City, which most definitely isn’t a short: more like a whole trilogy under one cover.

The Ultras are running away from Yellowstone and the Glitter Band after a virus, The Melding Plague, has destroyed everything by attacking all nano-machinery and implants. In this story we join a ship of Ultras and their hull-monkeys who are having some issues.
This is brilliant, yet so gruesome and twisted, you just have no idea how it’s going to end until you get to the end.
This is actually two separate stories and in the timeline between
What’s odd about this book is that it starts with an explanation of Yellowstone and the Glitter Band which would have been much better placed before 
A quick little short, bridging the gap between
Ok, if i’m feeling like being a bit picky — and i am feeling like that — then Alastair should have written a few more short stories and novellas to give a bit/lot more info about everything Glitter Band: and not the Gary type. One begins this story with not much background to go on and we seem to muddle through quite a bit until things get to be a lot clearer. I just think that background/info-dump things could have been laid out previously and given the reader a much more enjoyable time of it.
The fifth book in the Revelation Space series, and it’s a rather good one too.
The tension against the Demarchists is building and a spy is sent to Europa to retrieve a thing from a sleeper agent. But, as with
