Learn moreSeth is a surveyor, along with his friend Theo, a leech-like creature running through his skull who tells Seth what lies to his left and right.
In the universe containing Seth's world, light cannot travel in all directions: there is a "dark cone" to the north and south. Seth can only face to the east (or the west, if he tips his head backwards). If he starts to turn to the north or south, his body stretches out across the landscape, and to rotate as far as north-north-east is impossible.
Every living thing in Seth's world is in a state of perpetual migration as they follow the sun's shifting orbit and the narrow habitable zone it creates. Cities are being constantly disassembled at one edge and rebuilt at the other, with surveyors mapping safe routes ahead.
But when Seth and Theo join an expedition to the edge of the habitable zone, they discover a terrifying threat: a fissure in the surface of the world, so deep and wide that no one can perceive its limits. As the habitable zone continues to move, the migration will soon be blocked by this unbridgeable void, and the expedition has only one option to save its city from annihilation: descend into the unknown.

Paul Boehmer attended his first Shakespearean play while in high school; he knew then that he was destined to become the classically trained actor he is today. Graduating with a master's degree, Paul was cast as Hamlet by the very stage actor who inspired his career path. A nod from the Universe he'd chosen aright! Paul has worked on Broadway and extensively in regional theater. Coinciding with another of his passions, sci-fi, Paul has been cast in various roles in many episodes of Star Trek. Paul's love of literature and learning led him by nature to his work as a narrator for audiobooks, his latest endeavour. Paul is married to the love of his life, Offir, and they live in Los Angeles with their two midnight-rambling tomcats, Dread and David.
