Don Tillman

Meet Don. Don is a genetics professor who just might be somewhere on the autistic spectrum. He looks a little like Gregory Peck and 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. And it’s definitely not Rosie. Absolutely, completely, definitely not .Rosie, meanwhile, isn’t looking for love; she’s looking for her biological father. Sometimes, though, you don’t find love: love finds you...

With the Wife Project complete, Don settles happily into a new job and married life in New York. But it's not long before certain events are taken out of his control and it's time to embark on a new project. As Don tries to get to grips with the requirements of starting a family, his unusual research style soon gets him into trouble. To make matters more difficult, Don has invited his closest friend to stay with them.

Until 12 years ago, geneticist Don Tillman had never had a second date. Then he developed The Wife Project and met Rosie, 'the world's most incompatible woman'. Now, having survived 4,380 days of marriage, Don's life-contentment graph, recently at its highest point, is curving downwards. Rosie has just returned to work and is struggling with an obnoxious co-worker. Don, meanwhile, is in hot water after his latest lecture goes viral. But their real worry is their son, Hudson, who is having trouble at school: his teachers say he isn't fitting in with the other kids.
