"A heartwarming and refreshing debut novel that proves one thing: there's not enough data in the world to predict what will make your heart tick. Stella Lane thinks math is the only thing that unites the universe. She comes up with algorithms to predict customer purchases--a job that has given her more money than she knows what to do with, and way less experience in the dating department than the average thirty-year-old. It doesn't help that Stella has Asperger's and French kissing reminds her of a shark getting its teeth cleaned by pilot fish. Her conclusion: she needs lots of practice--with a professional. Which is why she hires escort Michael Phan. The Vietnamese and Swedish stunner can't afford to turn down Stella's offer, and agrees to help her check off all the boxes on her lesson plan--from foreplay to more-than-missionary position... Before long, Stella not only learns to appreciate his kisses, but crave all of the other things he's making her feel. Their no-nonsense partnership starts making a strange kind of sense. And the pattern that emerges will convince Stella that love is the best kind of logic.."--
A glimpse inside

Helen Hoang places an autistic protagonist, Stella Lane, at the heart of her story, challenging stereotypes about what neurodivergent characters can be in romantic fiction. Stella’s unique perspective shapes her approach to relationships, intimacy, and communication. The book doesn’t treat her autism as a hurdle to overcome, but as an integral part of her identity, inviting empathy and understanding. This representation is rare in mainstream romance, making the novel significant for its authentic, respectful portrayal of neurodiversity.
The novel uses the trope of a paid relationship—Stella hires Michael, an escort—to flip expectations about how love can start. What begins as a pragmatic arrangement for Stella to gain sexual experience evolves into genuine emotional connection. This progression highlights how vulnerability, honesty, and mutual respect can transform even the most calculated interactions into deep, meaningful bonds.
