This book starts with a very wacky premise. A young woman makes no permanent impression on the memories of anyone with whom she has contact. A person could spend hours talking to her and the minute they turn away they lose all memory of their experience with her. They can turn back and reintroduce themselves to her as if they never met. And from there the story goes through Hope's life. What does she do with this apparent gift? What does she do when the gift eventually becomes a curse? The premise is fascinating and North explores every aspect of this person's life while providing a compelling and addictive plotline.
