Back to Eden by Yuri Baranovsky

A man and woman find themselves in an empty space with nothing but a door and each other; their memory of their past is as vague as their memory of one another. When a businessman enters and offers to build them the world, they jump at the chance, hoping it will bring them some sort of happiness and control. But as they try to figure out what exactly they want and who they want to be, they also discover that perhaps they shouldn't have asked questions at all. A poignant and humorous reinterpretation of the story of Adam and Eve.
