The Rosie Project by Graeme Simsion

Don Tillman is a brilliant geneticist with Asperger's syndrome. So he's not the best at social interactions. Don decides it's time to find a wife. He sets about it in the highly organized, overly analytic way he does everything else. He creates a multi-page questionnaire to identify potential trouble spots such as smoking, drinking, being obsessed with one flavor of ice cream. His quest to find the perfect mate is not going well when he meets Rosie who, according to his exacting standards, is totally unsuitable. And yet, she's oddly irresistible. And so begins one of the goofiest, funniest courtships in history.

The Rosie Project is a sweet, quirky love story with some laugh-out-loud scenes. It's a perfect choice for this Valentine's weekend.
