Doctor Who Short Trips is a series of themed short story anthologies of new Doctor Who fiction, featuring the Doctor in all of his first eight incarnations. They feature stories written by some of the leading names in Doctor Who, past and present, including Paul Cornell, Gareth Roberts, Christopher H. Bidmead, and Paul Magrs. Steel Skies is a collection of stories based in enclosed and artificial environments--places constructed to keep the dangers of the universe outside, perhaps, or to keep their inhabitants locked in. It is divided into four sections, each exploring a different type or place of confinement: flight, futuristic frontiers, incarceration, and isolation.
