It’s very strange to realise you have written a serial killer." I argued 'he’s not a serial killer, he meets these terrible people and has these awful thoughts, but he’s very sensitive'. The author then clarified her position on the matter, citing that "I remember when I wrote You and someone first referred to Joe as a serial killer. Later, Kepnes was initially hesitant on labeling Joe, as a few readers argued that his actions classified him as a serial killer. Kepnes explained the darkness of You, which deconstructs the romantic-comedy tropes highlighted in many films and shows by making the protagonist a violent stalker and serial killer, saying it was written in a dark period of her life, the year her father died of cancer, and in which she experienced several other personal challenges. In 2014 Kepnes released her first novel of the thriller series, You.

In addition to her work as a writer, she performed as a background character in the television series The $treet. In an interview with the Boston Globe Kepnes said her first paid writing gig was an article on boy bands, for Tiger Beat magazine. Later, she obtained an undergraduate degree in American Civilization and worked as an entertainment reporter for Entertainment Weekly. After graduation, she commenced her studies at Brown University. Her father was Jewish and Kepnes identifies as " half-Jewish." During her formative years, she attended Barnstable High School. Kepnes was born November 1976 on Cape Cod, Massachusetts.

She is best known for her novel series You, consisting of You (2014), Hidden Bodies (2016), You Love Me (2021), and the forthcoming For You and You Only (2023), writing for the 2018–present Lifetime/ Netflix television series adaptation of the same name, and the stand-alone novel Providence (2018).
