George R.R. Martin is bringing more dragons to HBO with sci-fi series Roadmarks

Deadline

The Game of Thrones author is executive producing a TV adaptation of sci-fi novelist Roger Zelazny's 1979 sci-fi book Roadmarks. Kalinda Vazquez -- a Star Trek: Discovery, Fear the Walking Dead and Once Upon a Time writer-producer who was named after an original Star Trek series character -- will serve as writer and showrunner on the potential series. According to Deadline, Roadmarks "is about a highway that can travel through time, linking all timelines and places together for the very special people who discover it. Some might use it to explore the vast mysteries of the world, but for others…the road might be their only hope to survive, rewrite life-altering mistakes, and create a better future for themselves and the ones they love. The Road was created by the Dragons of Bel’kwinith and no one knows who they are or why they made it."
