Helen Hoang is born on 1982. and she is an American romance novelist, best known for her best-selling debut novel The Kiss Quotient. Helen Hoang was raised in Minnesota before moving to California. Her mother is a Vietnamese immigrant. Hoang's first novel, The Kiss Quotient, was published in June 2018. The romance novel follows Stella, an autistic woman who hires an escort in order to explore intimacy with other people. Hoang states that she initially wanted to write a gender-swapped Pretty Woman, but was stuck when examining why a "successful, beautiful woman would hire an escort." Later, her realization that she and her daughter are both on the autism spectrum led to the basis for the book. A sequel titled The Bride Test, about Esme, a hotel maid who gets offered to accompany Khai, the autistic cousin of Michael from the first book who never had a girlfriend before to weddings, was published by Berkley in May 2019. Hoang says that she wanted to subvert the harmful tropes surrounding autism by writing an autistic character through protagonist Khai who is perceived by others as cold and heartless when this is not actually the case. The book was inspired by her mother's immigrant story, with Esme’s story coming directly from conversations with her mom about what it was like to be poor in Vietnam and what it was like when she first came to the U.S. Hoang describes The Bride Test as "Green Card meets Four Weddings and a Funeral—but with autism." Hoang's third book in the series, The Heart Principle, was published in 2021. Hoang describes it as "a cross between a gender-swapped Sabrina and Say Anything."
