The Rosie result, by Graeme Simsion

The final book in the trilogy featuring Don Tillman, which began with The Rosie Project and his quest, at forty, to find a mate.  By book three, Don and Rosie have been married for years and have an eleven-year-old son, Hudson.  Rosie has accepted her dream job back in her home country of Australia, so they relocate from New York to Melbourne.  There Hudson has trouble fitting in.  Like his father, still technically undiagnosed after two other books that make it quite clear that he is “on the spectrum,” Hudson exhibits behaviors which make his new school’s administration conclude he may be autistic.  Hudson’s only friend is girl his age who lives with her anti-vaxer parents and is albino.   Don finds a new job at a university but is soon in trouble after a student accuses him of racism (a misunderstanding caused by his lack of social awareness) and is placed on leave.  With time on his hands, of all things, he starts a cocktail bar, one that will appeal to people, like himself, who are introverted, hate crowds, and are bothered by noise.  The book is both funny and thoughtful, and will speak to anyone, and lately that seems like most of us, who know someone, or are ourselves, a bit on the spectrum.  A nice ending to the series.  376 pp.
