From the New York Times and USA Today bestselling author Christina Lauren (‘The perfect choice if you’ve had to cancel your summer holiday but still want to feel the sand between your toes’ Beth O’Leary) comes a novel about what happens when a matchmaking company finds an ideal match in an unlikely pair.

Jess Davis is a numbers genius, but when it comes to love she’s had to accept there is no magic formula. Juggling a mathematical career with raising her hyper (but adorable) seven-year-old Juno, it’s not surprising that her love life is. . . non-existent. Juno has a hunch that her mum would find the perfect man if she stepped out of her comfort zone – but Jess barely has time to make her daughter’s lunch, let alone put thought into dating. And when yet another date ends in disaster, she’s prepared to give up on love for good.

But then she hears about GeneticAlly, a buzzy new matchmaking company that claims to find you the One using a DNA equation. Suddenly, love doesn’t seem quite so far out of reach . . .

Until her test shows an unheard-of 98% compatibility with GeneticAlly’s founder, Dr. River Pena. This is one number she can’t wrap her head around, because she already knows Dr. Pena, and this man is 100% not her soulmate. But GeneticAlly has a proposition: Get to know him and we’ll pay you. Jess, who is just about making ends meet, is in no position to turn it down. As the pair are dragged from one event to the next as the ‘Diamond’ pairing that could make GeneticAlly a fortune, Jess begins to realise that there might be more to the scientist – and the science behind a soulmate – than she thought.

The New York Times bestselling author of The Unhoneymooners returns with a hilariously witty and feel-good novel which proves once and for all that while data may be easy to crack, dating isn’t quite so simple . . . Perfect for fans of The Rosie Project and One Plus One.
