The Best of All Possible Worlds involves a science fiction setting vaguely reminiscent of Ursula LeGuin’s Hainish novels (mostly because the worldbuilding involves a loose federation of related humanoid species). Our protagonist is a woman named Delarua who has the task of assisting refugees settling on her home planet. During the course of the novel, she has various adventures and eventually enters a relationship with one of the refugees, a man named Dllenanakh. She also gets into a nasty family situation and an even nastier political one.
