Can a rigidly scheduled, highly prepared genetic scientist make his marriage work with a free-thinking, spontaneous wife? And what happens to Don's carefully calculated spreadsheets when an unexpected pregnancy adds another variable to the equation?
In this sequel to The Rosie Project, Australians Don and Rosie are married and living temporarily in America to teach and study, respectively, at Columbia in New York. It's a comedy of errors as Don tries (secretly, so as not to add stress and increased cortisol levels) to learn as much as he can about babies, pregnancy, and fatherhood.
Along with the return of the first book's supporting characters, this story adds a great new bunch of friends Don accumulates in New York. He's got a guy gang with whom he regularly schedules ballgame-and-beer nights, and they become his sometimes ill-advising support network as he tries to navigate Rosie's pregnancy hormones and some unfortunate legal concerns Don's hiding from his wife.
Overall it's a mad-cap fun story, and a lovely light diversion.
