The soulmate equation
(Book)

Jess Davis, a freelance statistician and single mother, is ready to swear off dating after her most recent lackluster outing. And nothing about River Peña, a grumpy if hot regular at her favorite coffee shop, tempts her to change her mind, especially after he insults her and makes an already terrible day worse. Yet somehow learning that he is a scientist who has designed a gene-based matchmaking product piques Jess? interest. On a whim, she provides a sample to the dating service and then is more than skeptical to learn that it identifies River as a nearly perfect match just when his company's IPO is mere months away. Jess' analytical and practical sides war with her desire to protect herself and her daughter, while River's dedication to his company means that his own romantic life has not been a priority, yet they decide to trust the science (and their attraction) and give a relationship a chance.
