The Rosie project, by Graeme Simsion

A short, amusing, and diverting tale of a bright but awkward man’s search for love via “The Wife Project,” a multi-paged survey designed to weed out smokers, annoying vegans, and others who might not fit into Don Tillman’s rigidly constructed world.  Yes, he’s very much “on the spectrum” and has just two friends, a married couple in an open marriage in which the husband is striving to have sex with at least one woman from every country in the world.  However, Don knows he’s odd and socially awkward and he is also more self-aware than one would assume.  Then he meets Rosie, who fails virtually every question on the survey.  She is looking for her biological father, who her free-spirited late mother has never named.  Don is a brilliant geneticist and his knowledge may help her surreptitiously test the field of candidates.   There’s a predictable happy ending.  Fun.  295 pp.
