Buffalo Soldiers producer Ilene Kahn Power and Elizabeth Stanley have secured the rights to the fantasy series.
"Set in a unique world and full of great adventure, the Darkover series truly has the potential to be must-see television for seasons to come," said Kahn Power. "The novels have a huge fan following throughout the science fiction and fantasy communities."
The Darkover series consists of several novels and short stories, all set on the fictional, far-flung world of Darkover.
Kahn Power added: "With the ability to create the Darkover world through state-of-the-art effects and the opportunity to utilise multiple platforms to unfold our narrative, now is the ideal time to create a lasting and far-reaching series that features compelling characters and gripping stories.
"[The series] will appeal not only to existing fans but also to the broader audience which has embraced series such as Game of Thrones and Battlestar Galactica."
Co-producer Stanley praised author Bradley for "her rethinking and reinvention of gender roles".
"She was among the first speculative fiction writers to take on gender stereotypes and bend them or turn them topsy-turvy," she suggested. "Thereby creating complex and unforgettable characters whose struggles with their own identities, as well as what society expects of them, feel completely modern."
Bradley's 1983 novel The Mists of Avalon - a retelling of the Arthurian legends - was adapted as a TNT mini-series in 2001, earning three Emmy nominations.
