‘Don Tillman helps us believe in possibility, makes us proud to be human beings, and…keeps us laughing like hell.'—Matthew Quick, New York Times bestselling author of The Silver Lining Playbook

‘Extraordinarily clever, funny, and moving.'—Bill Gates

‘Don Tillman…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. Through him, Simsion…deals with issues of nature, nurture, gender, free will and the vagaries of the human heart with a deceptively light touch.'—Evening Standard

‘A heartwarming story of an extraordinary man learning to live in an ordinary world.’—USA Today

‘[Don] Tillman has almost transcended the boundaries of fiction to become a geek icon.'—Guardian

‘There is much to love in this comedy of errors.'—Daily Express

‘Don himself, pedantically single-focused as ever, is increasingly charismatic and the left-field resolution of his problems is as satisfyingly credible as it is delightfully unexpected.'—Adelaide Advertiser

'The Rosie Effect is a celebration of the best attributes to be found in a friend, a husband, or a father, regardless of the way they are expressed.'—Booklist (starred review)
