The Game of Thrones creator is exec producing a TV adaptation of Roadmarks from sci-fi novelist Roger Zelazny, which is development at the WarnerMedia cable network.

The adaptation comes from Kalinda Vazquez, who has written on Star Trek: Discovery and was a co-exec producer on Fear The Walking Dead. Vazquez, who was named after a character from the original Star Trek TV series, will write, exec produce and showrun the adaptation.

The book was written in the late 1970s and published by Del Rey in 1979. It 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.
