In this epic sci-fi adventure for fans of The Expanse and Battlestar Galactica, five intrepid heroes must unite to save civilization after a long-dormant enemy awakens and strikes a devastating blow “This jarring, engrossing story of a species-wide fight for survival is recommended for all science fiction readers.”—Publishers Weekly (starred review) The galaxy was once terrorized by the Sturm, a group of “species purists” intent on destroying any human with genetic or cybernetic enhancements. Fashioning themselves as the one true “Human Republic,” the Sturm cut a bloody swath across the stars, killing billions before finally being defeated and driven into the far reaches of Dark Space. Centuries of peace bred complacency. Everyone believed the Sturm had died out in the Dark. They were wrong. The enemy has returned and, with a brutal and decisive attack, knocks out almost all of humanity’s defenses. Now on the brink of annihilation, humankind’s only hope is a few brave souls who survived the initial attack: Commander Lucinda Hardy, thrust into uncertain command of the Royal Armadalen Navy’s only surviving warship. Booker3, a soldier of Earth, sentenced to die for treason, whose time on death row is cut short when the Sturm attack his prison compound. Princess Alessia, a young royal of the Montanblanc Corporation, forced to flee when her home planet is overrun and her entire family executed. Sephina L’trel, the leader of an outlaw band who must call on all of her criminal skills to resist the invasion. And, finally, Admiral Frazer McLennan, the infamous hero of the first war with the Sturm hundreds of years ago, who hopes to rout his old foes once and for all—or die trying. These five flawed, reluctant heroes must band together to prevail against a relentless enemy and near-impossible odds. For if they fail, the future itself is doomed. “Frenetic action viewed in a black fun-house mirror.”—Kirkus Reviews

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 artefacts - 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.
