The charming, brilliantly funny new novel from the Sunday Times bestselling author Jenny Colgan. Connie's smart. She's funny. But she's only human . . . As a high-ranking mathematician in a male-dominated field - with bright red hair - Connie's used to being considered a little unusual. But she's nowhere near as peculiar as Luke, who is recruited to work alongside her on a top-secret code breaking project. Just what is this bizarre sequence they're studying? It isn't a solution to the global energy crisis. It isn't a new wavelength to sell microwave ovens. The numbers are trying to tell them something . . . and it seems only Luke knows what.The truth is out there. Will Connie dare to find it? In this whirlwind adventure, Sunday Times bestselling author Jenny Colgan boldly goes where no author has gone before . . . 'Quirky, funny and romantic, and it doesn't even matter if you don't know what fractals are' Sophie Kinsella. 'A riotous cocktail of action, maths geeks, and kissing. I enjoyed every single page. Resistance really is futile' Matt Haig, author of THE HUMANS.
