The Rosie Project tells the story of "one of the most unforgettable and endearing protagonists in contemporary fiction and a real one-off - Don Tillman".

"A genetics professor who might just be somewhere on the autism spectrum, Don defies reader's expectations of what it is to be 'normal', or who a romantic lead might be, and as he embarks on his unique quest to find a wife we find ourselves compelled to see the world through his eyes – his foibles, his unique insights on love and everything else and his penchant for lobster on Tuesdays – and fall a little bit in love with him."
