The Rosie Project by Graeme Simsion ***

An associate professor with Asperger's sets up a questionnaire to find a wife. Rosie and Dan become very close, but he considers her completely unsuitable as a life partner, and sets out instead to find out who her biological father is. A delightful novel, easy to read, with a good narrative. there's some wonderful scenes, especially the cocktail party where Dan serves all these weird cocktails to professors.
