Son's father, Yong Sup Son, and mother, Soon Chum "Ruby" Son, were both from Korea.[5][6] Son's mother came to the United States in 1963.[5] She had six sisters in Korea.[4] Son's parents met in Philadelphia, where her father was a student at the College of Pharmacy (now the University of the Sciences) and her mother was an exchange nurse at Lankenau Medical Center.[6] They moved to Dover in 1967, where they owned and operated the Town Drug Store in the Milford Shopping Center in Milford, Delaware.[5] Son grew up working in the drug store.[2]
Son's first play was called Wrecked On Brecht and was published in 1987.[9] For eight to 10 years, she wrote and produced short plays in the downtown area of Manhattan.[4] Her play BOY premiered at La Jolla Playhouse in 1996 and was directed by Michael Greif. The storyline for BOY is based on Son's mother's family adopting a male cousin.[4] It is a story in which a young girl's parents decide to raise her as a son.[4] In 1998, her play Fishes premiered at New Georges in New York City. Son wrote the short play R.A.W. ('Cause I'm A Woman), which explores how men view Asian American women.[4]
Her first full-length play, Stop Kiss, debuted in 1998.[4] It was critically acclaimed.[10][11] The play was produced Off-Broadway in 1998 at The Public Theater in New York City. It was extended three times.[12] The play's initial run featured Jessica Hecht, Saul Stein, Sandra Oh, Saundra McClain, Kevin Carroll, and Rick Holmes. Son met Oh—who has participated in readings of every play by Son since they met—in 1995 in Los Angeles while involved in the New Works Festival.[13] The play features two women who kiss on the street, and are "grievously injured" in an attack.[4] Themes include gay bashing and identity.
After the first night's performance of Stop Kiss, Son realized she would no longer have to do "copyediting, proofreading, waitressing, and temping"—jobs she took to support herself before the play came out.[4] It has since been produced by hundreds of theaters.[7] In 2014, Stop Kiss was produced at the Pasadena Playhouse, where it made the Los Angeles Times' "Best of 2014" list.[14]
In March 2015, Son began work on the ABC series American Crime.[20] At the 2015 TCAs, NBC ordered the pilot for Love is a Four Letter Word.[21] It will be produced by 20th Century Fox Television and Red Arrow’s U.S. scripted arm, Fabrik Entertainment.[22] Son will write and executive produce with Mikkel Bondesen and Kristen Campo.[23]
