Million-copy-selling Chris Brookmyre takes his fiction further than ever before in this wildly inventive and sharply-plotted novel set in the unforgiving emptiness of space.

**LONGLISTED FOR THE MCILVANNEY PRIZE FOR CRIME WRITING 2018**

"This is as close to a city without crime as mankind has ever seen."

Ciudad de Cielo is the 'city in the sky', a space station where hundreds of scientists and engineers work in earth's orbit, building the colony ship that will one day take humanity to the stars.

When a mutilated body is found on the CdC, the eyes of the world are watching. Top-of the-class investigator, Alice Blake, is sent from Earth to team up with CdC's Freeman - a jaded cop with more reason than most to distrust such planetside interference.

As the death toll climbs and factions aboard the station become more and more fractious, Freeman and Blake will discover clues to a conspiracy that threatens not only their own lives, but the future of humanity itself.
