Dune / Frank Herbert 412 p.

Book one in the Dune novels, main series is set on a desert planet Arrakis.  It is a desirable planet because of its mining operations for spice.  The Duke of Ledo is murdered when a warring faction seek to take charge of the operation.  Paul Altreides with his mother escape and live with the Fremen who come to believe that Paul is a savior.  He evolves into the Muad'Dib, a person with great powers above what his somewhat mythical witch mother has.  He seeks revenge against his father's murder,  Baron Harkonnen.  War erupts and Paul's young sister kills the Baron and his young son is killed.  What makes this of interest to me is the ecological theme.  Survival on a desert planet depends upon water and the people of Arrakis have developed many ways to conserve and reuse water.  This may satisfy advanced sci-fi readers.
