‘Funny and heartwarming, a gem of a book.’

‘The Rosie Project is 1930s screwball comedy updated for 2013. Hepburn and Grant in Bringing Up Baby, or Rosalind Russell and Grant in His Girl Friday have the exact same pitch, intelligence, wit and farce with a love story at the centre of it all. Madcap indeed, but like those films The Rosie Project underscored with writing meticulously judged…Extremely loud and incredibly long applause.’

‘What an endearing, funny book…a quirky love story about belonging with poignant undertones on the need for us all to be more tolerant of those with differences. A must read.’

‘The charm of this story is Simsion’s affectionate depiction of his strange, flawed, infuriating, logical and always amusing protagonist.’

‘Laugh-out loud funny, poignant and so ingenious and compelling you feel as if you want to jump into the world of the novel and join in. In Don’s confessionals, there are echoes of Bridget Jones, writer Nick Hornby and Amelie in the French movie hit…but essentially Don Tillman is utterly and beautifully unique and, be warned, you will fall in love with him.’

‘One of the quirkiest, most adorable novels I’ve come across…This is a fresh, funny story, written with verve and great timing…I loved The Rosie Project. It’s an entertaining read from start to finish, thoughtful and fun, very different and utterly charming - a brilliant first novel from a mature, clever writer.’

‘Graeme Simsion has created perhaps the first thoroughly comic autistic hero…This good-hearted, pacy, thoroughly enjoyable novel takes a significant step towards showing that all human variants are a potential source of life‑affirming comedy.’

‘Funny, endearing, and pure, wonderful escapism, this debut tells the story of the logical Professor Don Tillman and his unscientific search for a wife.’

‘…Simsion has fashioned a very funny and touching love story…he has provided a clever satire on modern, internet-led dating, demonstrating that finding the right partner is not about the ticking of boxes, but something else: chancing upon something flawed and intangible and great, which burns like a mysterious fire.’

‘Imagine the literary equivalent of one of those lamps prescribed for sufferers of seasonal affective disorder—a book that found the crack in our seemingly interminable winter to let laughter and light flood in.’

‘[Don Tillman is] one of the most endearing, charming and fascinating literary characters I have met in a long time.’

‘Crackling with wit and boasting an almost perfectly calibrated heartbreak-to-romance ratio, Graeme Simsion’s delightful debut, The Rosie Project, joins ranks with the best romantic comedies of our age.’

‘An extraordinarily clever, funny, and moving book about being comfortable with who you are and what you’re good at. I’m sending copies to several friends and hope to re-read it later this year. This is one of the most profound novels I’ve read in a long time.’

‘The love story between autistic geneticist Don and Rosie is as awkward as it is heartwarming, and it is hard not to wish for the best for this odd couple.’

‘As well as being delightfully romantic, this is a very funny book and you’ll be laughing out loud at Don’s misadventures.’

’Quietly profound.’

‘Cinematic flourishes and cliffhangers run through this brisk, funny, and at times outrageous story…Don and Rosie’s companionable sparring, and their wider circle of colleagues, make for a completely charming story that is as engaging as it is funny.’
