Knoll’s sophomore novel, The Favorite Sister, debuted three years later in 2018, producing yet another suspense-filled page-turner. Knoll is currently in the process of adapting her second novel, and it was also recently announced that she’s adapting the Reddit short story “I Think My Mother-in-Law Is Trying to Kill Me” for Sony. And she’s not stopping there. She’s also written and sold her first original script, Til Death, to Amazon, making history as the first-ever original script purchased by the streamer.
