The Impossible Knife of Memory, Laurie Halse Anderson’s latest teen novel, tells the story of Hayley Kincain and her father. Hayley’s mother died when she was a baby, and ever since it’s just been Hayley and her dad. When Hayley’s father returns from war with severe post-traumatic stress disorder, her life gets turned upside down. In order to deal with the memories that haunt him, he becomes a truck driver, driving all over the country trying to outrun his memories. After years of homeschooling Hayley on the road, he decides they should move back to his hometown. Since they set out on the road years before, Hayley has had to be the responsible one, taking care of herself and her father. She hopes that moving home will mean that their life will settle down. Her father isn’t getting better at home either. He continues to self-medicate his PTSD with drugs and alcohol, forcing Hayley to run the house and keep her teachers and friends from noticing.
At school, Hayley struggles to deal with her zombie-like classmates and teachers who don’t accept her unorthodox education. Her only friend is Gracie, a friend from elementary school who barely remembers her. Finn, another classmate, has made it his mission to get Hayley to write for the school newspaper in order to become closer to her. As she begins to fall for Finn, her father takes a turn for the worse and her life falls to pieces.
Much like Anderson’s earlier novel Speak, The Impossible Knife of Memory deals with many heavy themes. Hayley’s distinct voice and vibrant personality make her a character readers will identify with and remember long after they finish the book.
