What does it mean to be human when you can't prove you are one? He wakes up on a ship in the middle of deep space with no memory of who he is. He doesn't know yet what the answers will cost him. What Remains Upon Arrival is a psychological sci-fi thriller about identity, manipulation, and the question of what makes someone human. A truth that gets darker with every piece that falls into place. The mission was supposed to save humanity. It was never that simple.

Since time immemorial, angels have ruled the world. Humans, animari and even demons . . . all but shiver at the sight of those winged creatures ancient and without conscience - ancients and without conscience. Now, violent and eerie events around the world threaten to wipe out entire civilizations: the sky roar, seas boil, the earth shake. Among the surge of devastation stands Yavannah. A demon, a traitor . . . nothing the world would miss - and yet, something is chasing him and won't stop until his nightmares come to life again.

Deep beneath the Humber's poisoned tides, Commander Fallon and the crew of the Vanguard fight to keep their dying submarine alive long enough to warn what remains of the world. But every attempt to reach the surface comes at a cost and the enemy above is evolving faster than they can adapt. Armoured units now stalk the ruins of Britain's east coast, building something vast, something deliberate, something that pulses with a cold, blue light. On land, Cairn and his fractured band of survivors cling to the fragile safety of an abandoned ambulance station. But safety is an illusion. The chrome hunters are learning. The nights are growing longer. And the death of one of their own sends shockwaves through the group that no one is prepared to face. Far from them all, in a place that is not a place, Blue is being remade. Dragged through visions of alien worlds and dead Mothers, she is forced to confront the truth of her creation - and the terrifying beauty of the being who calls himself Father. His voice is everywhere. His pull is irresistible. And his plans for her are older than the monoliths themselves. Book 3 is in development

Nineteen is meant to be the year of bad decisions. For Pauline, it should have been a year of hangovers on Newland Avenue and crying over boys who don't text back. Instead, she's scraping cold tins of food in a boarded-up Sainsbury's, running from a sky that has turned the color of fire. ​For Cairn, the world ended at a train station. There were no sirens, just a news report that London was gone-wiped off the map in a heartbeat. Now, the veteran soldier leads a rag-tag pack through the ruins of York, clinging to the shadows of a country that no longer exists. Fight for survival is happening beneath the waves. The HMS Vanguard, a billion-pound fortress of steel and nuclear fire, is drifting in a silent ocean. With London in ashes and the chain of command severed, the crew of the Vanguard are the last ghosts of a dead nation, struggling to keep their vessel alive while the world above them burns. ​Three paths are about to collide in the wreckage of the North. Book 2 is now out, After The Stars Fell
