I think this story can be seen in a number of different ways - as a purr adventure story, one of self-fulfillment and empowerment or as a metaphor for a life lost to personal pursuits and its gains and losses or as an exploration of the famous quote, "not all who wander are lost", or even as a consideration of the story of mankind which wonders what more worlds are there to conquer? 

An slim, quick-moving, accessible novel which maybe promises more of an intellectual or symbolic tale than it ultimately ends up provided.
