The second novel, Welcome To Planet Moon, takes  place in the distant future after a mechanical failure leaves two surviving crew marooned on a desolate wasteland, with an abandonded city beneath the barren surface. Searching for a means of rescue, and encountering the remnants of an advanced civilization, they encounter nothing deep within the dead world.
