Meet Don Tillman. Don is getting married. He just doesn't know who to yet. But he has designed a very detailed questionnaire to help him find the perfect woman. One thing he already knows, though, is that it's not Rosie. Absolutely, completely, definitely not. Don Tillman has got his love life planned out. He knows exactly who he wants, but is it who he needs? Love isn't an exact science - but no one told Don Tillman. A thirty-nine-year-old geneticist, Don's never had a second date. So he devises the Wife Project, a scientific test to find the perfect partner. Enter Rosie - 'the world's most incompatible woman' - throwing Don's safe, ordered life into chaos. But what is this unsettling, alien emotion he's feeling?
