The son of a poor widow, François Burnens is overwhelmed with his good fortune when he is hired to assist the gentleman-scientist, François Huber. Blind since the age of 19, Huber studies bees, helped by his wife in his observations at their Geneva home. Now expecting their second child, the couple realizes that she must concentrate on the family. Through Burnens's diary, from 1785 to 1794, the young man grows as a scientist, a writer, and a human being. Charles Bonnet and other scientists visit in person or in citation.
The domestic drama of the home plays against a backdrop of the menacing turbulence in nearby France. Burnens' admiration, respect and pity for Huber keeps him in the modestly-paid employ for nine long years. But his fascination with an artistically talented young woman shows him that his situation as a valued servant must come to an end.
