Two reporters looking for a story in the outer reaches of the Solar System come upon a derelict spaceship. Inside, they find the only inhabitant, a beautiful young woman who has been imprisoned for a thousand years in suspended animation, suspended but aware for the whole time. Together they set off on a grand adventure across the vastness of space and time in a search for a race known as the Cosmic Engineers on a mission to save the universe. Originally published as a short novel in Astounding Stories in 1939 and later expanded in this 1950 version, Cosmic Engineers shows the scope and imagination of one of science fictions true masters, Clifford Simak.
