The Arthur C. Clarke award-winning author of Children of Time brings us an extraordinary space opera about humanity on the brink of extinction, and how one man's discovery will save or destroy us all.

The war is over. Its heroes forgotten. Until one chance discovery....

Idris has neither aged nor slept since they remade him in the war. And one of humanity's heroes now scrapes by on a freelance salvage vessel, to avoid the attention of greater powers.

After Earth was destroyed, mankind created a fighting elite to save their species, enhanced humans such as Idris. In the silence of space they could communicate, mind-to-mind, with the enemy. Then their alien aggressors, the Architects, simply disappeared - and Idris and his kind became obsolete.

Now, 50 years later, Idris and his crew have discovered something strange abandoned in space. It's clearly the work of the Architects - but are they returning? And if so, why? Hunted by gangsters, cults and governments, Idris and his crew race across the galaxy hunting for answers. For they now possess something of incalculable value, that many would kill to obtain.

The Arthur C. Clarke award-winning author of Children of Time brings us the second novel in an extraordinary space opera trilogy about humanity on the brink of extinction, and how one man's discovery will save or destroy us all.

After eighty years of fragile peace, the Architects are back, wreaking havoc as they consume entire planets. In the past, Originator artifacts—vestiges of a long-vanished civilization—could save a world from annihilation. This time, the Architects have discovered a way to circumvent these protective relics. Suddenly, no planet is safe.

Facing impending extinction, the Human Colonies are in turmoil. While some believe a unified front is the only way to stop the Architects, others insist humanity should fight alone. And there are those who would seek to benefit from the fractured politics of war—even as the Architects loom ever closer.

Idris, who has spent decades running from the horrors of his past, finds himself thrust back onto the battlefront. As an Intermediary, he could be one of the few to turn the tide of war. With a handful of allies, he searches for a weapon that could push back the Architects and save the galaxy. But to do so, he must return to the nightmarish unspace, where his mind was broken and remade.

What Idris discovers there will change everything.
