A WARRINGTON writer’s books have been turned into a Netflix series.

The Bastard Son and the Devil Himself is an eight-part series based on Sally Green’s book series, Half Bad, which was released last month.

The Grappenhall resident's fantasy story Half Bad was the bestselling UK young adult debut novel of 2014.

And now the adaption is available to watch on Netflix.

The series adaptation is about the son of a notorious witch who is responsible for a deadly massacre.

Caught between two warring clans, he tries to find his place in the world – and his powers.

Sally started the Half Bad series in 2010. She had not written fiction since her O-Levels but found time on her hands when her son Indy was at school.

Since discovering her love of writing more than 10 years ago, now she ‘can’t stop’.

The idea for Half Bad originally cast its spell on Sally when she allowed her mind to wonder while going for walks in Lumb Brook wood.

Sally, who has lived in Warrington for nearly 30 years, previously told the Warrington Guardian: "If I need to think quietly about the book then I will go for a walk there.

"I also go up to Grappenhall Heys Walled Garden. It’s really peaceful."
