Helen Hoang is a New York Times bestselling author of the Kiss Quotient series: The Kiss Quotient, The Bride Test, and The Heart Principle. While these books are considered a series, they are loosely connected and do not require you to read the previous books in order to understand the later books. These books are also steamy romance reads. Helen has been obsessed with romance books since eighth grade. She currently lives in San Diego with her family.

What drew me to Helen Hoang’s novels is her relationship with Autism Spectrum Disorder. In 2016, Helen was diagnosed with Autism Spectrum Disorder, specifically what was previously known as Asperger’s syndrome. In each of her books, at least one of the main characters is diagnosed with Autism Spectrum Disorder. Helen’s knowledge of this disorder is clearly present when she writes each of those characters and how they interact with the world.

The Kiss Quotient is the first book in this series. Stella Lane loves math. She believes that math is the only thing that makes the universe make sense. In her job, Stella comes up with algorithms to predict customer purchases. Her job gives her more money than she knows what to do with, but unfortunately doesn’t help her at all in the dating department. You see, Stella has Asperger’s syndrome. She doesn’t necessarily want to date, but recognizes that she needs practice. She is wealthy and successful, but one-on-one interactions with people are awkward for her.

Wanting to get more practice, Stella decides to hire a professional, escort Michael Phan. She wants Michael to teach her how to be a good girlfriend and comes up with a detailed lesson plan of what she wants to learn. Michael has mounting bills and a hard rule that he doesn’t take repeat customers. When Stella presents him with an unconventional proposal, he decides that he can’t turn her down. What starts as a no-nonsense partnership starts changing when they fall into a pattern. Michael and Stella spend more time together, learning more about each other as they work through Stella’s list. Stella starts to grow on Michael, while Stella learns that love isn’t something that can be quantified.
