Katydid draws us irresistibly into the reality of Kate, a nineteen-year old who is living with cerebral palsy. She is trouble. She is manipulative. She is bitchy. Yet her sharp wit and fighting spirit endear her to us. A young man, Ben, arrives into this disabled woman’s life. Kate seizes on Ben as an accomplice in her struggle for independence. Meanwhile, Dad and Mum deal with their own demons. Dark humour permeates Lucy O’Brien’s acute examination of a life fraught with family dysfunction.
