Lively will play the book's main character Lily Bloom and Baldoni will play Ryle Kincaid, the man Lily falls for. The book touches largely on domestic abuse, which Hoover has previously said was inspired by her mother's escape from her own abusive relationship.
In her TikTok video, Hoover showed her fans the house she grew up in "from the age of probably 4 to 18."
"I just want everyone to know how appreciative I am to my mother, who got us out of a scary situation when I was little and brought us here to this house," she explained.
