The Rosie Effect is the charming and hilarious sequel to Graeme Simsion's bestselling debut novel The Rosie Project.
Forty-one-year-old geneticist Don Tillman had never had a second date before he met Rosie.
Now, living in New York City, they have survived ten months and ten days of marriage, even if Don has had to sacrifice standardized meals and embrace unscheduled sex.
But then Rosie drops the mother of all bombshells. And Don must prepare for the biggest challenge of his previously ordered life - at the same time as dodging deportation, prosecution and professional disgrace.
Is Don Tillman ready to become the man he always dreamed of being? Or will he revert to his old ways and risk losing Rosie for ever?
Join Don and Rosie in the next chapter of their weird and wonderful journey in Graeme Simsion's unmissable new novel, The Rosie Effect.

Praise for The Rosie Effect:
'A wholly absorbing, vivid read that leaves you pining to be reunited with its characters every time you put it down - if you're able to'
Independent

'Don Tillman is the protagonist who keeps on giving. He is a gem, an empirical laser trained on human shortcomings, especially male ones, and even more especially his own. He is also utterly charming in his lack of guile and his belief in improvability . . . blissfully comic'
Evening Standard
'Simsion is very smart at negotiating the line between a satire of the whole modern baby-rearing neurosis and drawing intriguing characters . . . this book is an intelligent piece of fun'
The Times
'Offers plenty more laugh-out-loud moments'
Guardian
'Touching and entertaining'
Mail on Sunday
'Quirky and sweetly funny, you will want to join the Don Tillman fan club all over again'
Sun on Sunday
'Genuinely heartwarming, truly endearing, plenty of LOLs. You may end up a blubbing wreck'
Heat
'There is much to love in this comedy of errors'
Sunday Express
'If you loved The Rosie Project, I don't see how you could fail to love this funny, poignant sparkler of a novel too'
Woman & Home
'Equally heart-warming and hilarious'
Good Housekeeping
'The hilarious follow-up to The Rosie Project, one of the best novels I've read in ages. There's no sophomore slump here . . . It's a funny novel that also made me think about relationships. A sweet, entertaining, and thought-provoking book'
