The Rosie Project by Graeme Simpson

A first-date dud, socially awkward, and overly fond of quick-dry clothes, Don Tillman has given up on love. Until a chance encounter gives him an idea. He will design a questionnaire—a sixteen-page, scientifically researched questionnaire—to uncover the perfect partner. She will most definitely not be a barmaid, a smoker, a drinker or a late-arriver.  Rosie is all these things. She is also fiery and intelligent, strangely beguiling. And looking for her biological father—a search that a DNA expert might just be able to help her with.
