Don Tillman

A first-date dud, socially awkward, and overly fond of quick-dry clothes, genetics professor Don Tillman has given up on love, until a chance encounter gives him an idea. He will design a questionnaire to uncover the perfect partner. She will most definitely not be a barmaid, a smoker, a drinker or a late-arriver. Rosie is all these things. She is also fiery and intelligent, strangely beguiling, and looking for her biological father - a search that a DNA expert might just be able to help her with.

Don and Rosie are back in Melbourne after a decade in New York, and they're about to face their most important project. Their son, Hudson, is having trouble at school: His teachers say he isn't fitting in with the other kids. Meanwhile, Rosie is battling Judas at work, and Don is in hot water after the Genetics Lecture Outrage. The life-contentment graph, recently at its highest point, is curving downwards.
