What is the author's style in Sarah Kane: Complete Plays by Sarah Kane?

Sarah Kane's writing is invariably working and lower-middle-class British in its dialect and viciously vulgar in its execution. It reflects a uniformly gritty sense of time and place. Kane's characters exist in an unforgiving world, the world of awful news reports we hear and try to forget. It is a world of incest, war atrocities, suicide, and heartbreak.
