White Dwarf (1995)

In a distant future New York medical student Driscoll Rampart accomplishes his
internship at Rusta, a rural planet that doesn't revolve around its axis and
therefore is divided into contrasting halves of eternal day vs. eternal night.
One is a Victorian-styled colony, the other a medieval kingdom. Both leave Rampart
in a state of constant wonder, as he finds his way among humans and aliens, strange
dreams and even stranger reality, a dark keep and a red sea, and more universal
matters of war and peace, good and bad, love and hate and sickness and health.
