Graeme Simsion's Rosie Project was a fun read. Told in first person by Don Tillman, a genetics professor in search of wife. The catch? It's clear early on that Don Tillman has some degree of Asperger's (in fact, he reminded me a lot of Sheldon from Big Bang Theory). He wants a wife because studies have shown benefits for men, but his hyper-logical approach is to create a detailed questionnaire for prospective dates to fill out. Not surprisingly, he has few takers. So when Rosie--a smoking, chronically late bar-tender who's clearly not a wife prospect--shows up with questions about her paternity, he allows himself to be side-tracked. But his carefully laid plans don't account for Rosie at all, and before long, she's unsettled his entire life.
I was initially put off by Don's voice, but I have to admit he grew on me. There is some language (esp. when Rosie shows up), but it was a cute romance.
