How many movies have been made about Ted Bundy? Here's how the author came up with the idea for Bright Young Women

Jessica Knoll's third novel, Bright Young Women , is out Sept. 19 .

The author was inspired by Netflix 's 2019 documentary Conversations with a Killer : The Ted Bundy Tapes.

She says she was frustrated when she found little-to-no information about the victims of Bundy's crimes.

Knoll revealed she recently finished the first draft of her next novel.

She also teamed with Mila Kunis to adapt The Favorite Sister into a TV series.

Bright, Young Women is available on Sept. 19 .

She says adaptation of her novels is a bonus, not the end goal.
