Sarah Lotz is a screenwriter and novelist who pens novels under the name S.L Grey with author Louis Greenberg; YA novels with her daughter, as Lily Herne; and is one third of pseudonymous author Helena S. Paige. Lauren Beukes calls her 'a natural-born storyteller. Like the hand reaching up from the dark well, she'll drag you into her thrall. You'll come up gasping.' Sarah lives in England with her family and other animals.
