It's the year 2400. Toba has erupted and plunges the earth into a cold, dark volcanic winter. The world is divided into two factions, Denizens who opted to go underground, and the Solarians who remain on the surface. But there is something more than sinister in the air; children have developed kinetic powers, which, used in the wrong hands, could decimate all of humanity. Governments all around the world want them. But Commander Gideon Kinsman won't have any of that. He's prepared to do anything to stop them in their tracks and risk losing friends and colleagues. More than this, he must be prepared to face the ultimate choice; choose the children, or lose the man he loves more than anything in the world.
