Katie Kitamura’s “A Separation” hasn’t hit shelves yet, but the novel has already found a fan in Katherine Waterston. The “Fantastic Beasts and Where to Find Them” actress has acquired the film rights to the highly anticipated novel, set to be released by Riverhead Books next week. Deadline reports that the Waterston will star in the adaptation of the well-reviewed mystery.

“A Separation” — which bears no connection to Asghar Farhadi’s Oscar-winning film of the same title — follows “a young woman who has agreed with her faithless husband that it’s time for them to separate,” Deadline writes. “As she begins her new life, she gets word that her husband has gone missing, the jumping-off point for a searing, suspenseful story of intimacy and infidelity.”

The book has earned comparisons to Gillian Flynn’s bestseller “Gone Girl,” the source material for the 2014 box office hit of the same name. No word on who will pen the script or direct just yet.

Waterston’s previous credits include “Steve Jobs,” “Boardwalk Empire,” and “Night Moves.”

You can still catch “Fantastic Beasts and Where to Find Them” in theaters. The “Harry Potter” spinoff has grossed more than $800 million worldwide. Waterston plays an underemployed magical investigator in the film, which is set in the 1920s. In preparing for the role, she found inspiration from her grandmothers’ experiences. “One of them was a secretary in New York and took the elevated trains that are no longer in the city but are in our film,” Waterston revealed. “I thought about her, a young woman in New York, and my other grandmother who was a total punk and was, obviously, a pre-feminism feminist… And was an artist, and was very independent-minded and courageous and smart,” she explained. “It didn’t seem to me that it’s improbable that there were women like this back then. There’s always been women like that, I think.”
