2110. Earth is suffering major resource shortages, and the impact of climate change is peaking. Colonies have been established on Mars and the Moon, but these cannot hope to sustain any more than hundreds of citizens. Attention has turned to the need to discover an extra-solar colony world. Scientists have identified the means of creating a wormhole in the space-time continuum, which would allow interstellar travel. However, to do so they must first physically transport one end of the wormhole to where they want it to be, so setting up a wormhole will always rely on physical travel. A ship is sent to Mu Arae, earth-like planet discovered ten years before. It is a journey that will take eighty years, the crew, who will set up the wormhole on the planet, kept in suspended animation. But only a few years into the trip, the ship blows up, killing all aboard. 2190, eighty years after the starship set out. Gordon Kemp is a detective working in the cold case department in London. He has been assigned a murder investigation closed, unsolved, over eighty years ago. What he unearths will change history and threatens everything we know about what the powers that be have planned for Earth.
