Jess Davis is a freelance statistician and single mother in San Diego, raising her young daughter Juno with help from the grandparents who raised her. Pragmatic and data-driven, she is wary of romance -- but on a bad day, prompted by her best friend Fizzy, she submits a DNA sample to GeneticAlly, a buzzy company claiming it can scientifically identify romantic compatibility. The result is unprecedented: a 98 percent match, the highest the company has ever recorded -- with its co-founder, Dr. River Pena, a man Jess has already met at her local coffee shop and found cold and arrogant. Eager to prove its science and boost its valuation, GeneticAlly offers to pay Jess to date River publicly as their headline match. Strapped for money and deeply skeptical, Jess agrees. As she and River are paraded through company events, she begins to see past his stiff exterior and to question her own resistance to the idea that data could predict love. Told from Jess's perspective, the story balances a science-driven premise with single-parenthood, a warm supporting cast, and a slow reckoning with vulnerability.
