A first-date dud, socially awkward and overly fond of quick-dry clothes, genetics professor 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.

The Rosie Project is a romantic comedy like no other. It is arrestingly endearing and entirely unconventional, and it will make you want to drink cocktails.
