FX is ready to get its fairy tale on.

After a competitive situation with multiple outlets bidding, the cable network is adapting Victor LaValle's 2017 novel, The Changeling, for the small screen.

The Changeling is described as a fairy tale for grown-ups. Set in a New York no one knew existed, the drama focuses on the death-defying odyssey of Apollo Kagwa and Emma Valentine as they look to find out what happened to the son who was removed from them. On their voyage, they will travel through enchanted isles and haunted woodlands, meet glowing witches, demon giants and racist cops. They will deal with the perils of personal technology and social media, toxic masculinity, the mental health of new mothers and fathers, and find out if surviving a fairy tale is as brutal as simply surviving in Trumplandia.

The series is a co-production between FX Productions and Annapurna Television.

Kelly Marcel (Venom, Fifty Shades of Grey, Terra Nova) is attached to pen the script. The project hails from Annapurna Television, the independent studio behind the Fox drama pilot Mixtape and Netflix's upcoming scripted anthology The Ballad of Buster Scruggs from the Coen brothers. It is the latest small-screen effort to come from Annapurna, which is also prepping a TV series based on the alleged sex-trafficking cult Nxivm. Sue Naegle serves as president of the Megan Ellison-led Annapurna Television, helping the small-screen-focused arm of the company behind the features Sausage Party and Everybody Wants Some build a slate for broadcast, cable and digital platforms. Naegle is a former president of HBO Entertainment. The company has Hulu's Carrie Brownstein comedy pilot in the works.

For his part, LaValle has authored four novels: Changeling, The Ecstatic, Big Machine and The Devil in Silver. He is repped by CAA and Watkins/Loomis.

Marcel is with WME, Casarotto and Sloane Offer.
