Don Tillman is back!

The Rosie Project, Graeme Simsion's first novel, was an international publishing phenomenon. Now Graeme Simsion returns with the highly anticipated sequel, The Rosie Effect.

Don Tillman and Rosie Jarman are now married and living in New York. Just as Don is about to announce that Gene, his philandering best friend from Australia, is coming to stay, Rosie drops a bombshell: she's pregnant.

In true Don style, he gets all the technicalities right but all the emotions wrong—and risks losing Rosie when she needs him most.

Meet Graeme Simsion when he introduces The Rosie Effect.
