About the book: 2015 / Michael John Harrison is a British science fiction writer who knows how to harmoniously combine phantasmagoric pictures, choreographically refined action and deep psychologism. His trilogy, begun by the inimitable “Light”, is continued by the equally whimsical and multifaceted “Nova Swing”. A few years after Ed the Reader's fateful journey to the Kefauchi Tract, the Halo became a tourist route, and the Tract began to expand and change, touching the Earth with its areas and creating Zones where the Universe decided to take a break from the laws of physics. Mysterious artifacts and organisms leak out from there, living algorithms escape, capable of provoking unpredictable changes. To prevent these disasters, the Zone Police exists to counteract the adventurers and so-called "travel agents" who can control - or think they can - the distorted physics, skewed geography and psychic attacks of the Zone. And one day, a mysterious and at best only half-biological phenomenon finds a loophole into the normal world.
