This was a great book exploring how the age old question, can opposites fall in love? Don is a brilliant scientist, but autistic and socially inept. Reminds me a bit of the tv show 'The Good Doctor.' Don sets out to find a wife who meets his exact criteria. Each candidate must complete a complicated questionaire to be in the running. But all candidates fail. Instead, Don ends up meeting Rosie, a bartender, who fails even the beginning questions. Definitely not a match, and yet.......? Witty, believable characters who learn to adjust and accept each other, while impacting others around them. Enjoyable reading.
