After an experiment into telekinesis and the power of the mind, Duncan Wemyss finds himself transported to a terrifying new world. A planet with an absolute "up" and "down", a place where lower latitudes tilt ever more wildly towards an infinite drop into the abyss of deep space. Topland, the territories around the North Pole, are the only level spaces and fiercely defended against the invaders from below. Desperate to escape their precarious existence on the fantastic gradients of the South, the monstrous creatures of the lower latitudes launch an invasion of the North. Duncan is thrust into the middle of a violent war and forced to call on talents he never knew he had, talents the Northerners need for their very survival. The Slant is a fantastic novel about an ordinary human forced to survive in an alien environment, a world so extreme its inhabitants have to struggle and fight each day for their survival. The story recalls the sense of wonder created in masterpieces such as Rendezvous with Rama and Ringworld. Robert Gibson evokes the golden age of Science Fiction.
