Book excerpt: When Sybill Hess drives over to the hypnotist’s office, she hopes he can cure her of the headaches interrupting her sleep the way her friend Betty once saw a woman on TV cure a woman’s stammer. But what Dr. Diamond uncovers from Sybill’s subconscious goes much deeper than her nervousness over a new tenant who seems to want a date. A shocking memory from Sybill’s past threatens to upend everything she thinks she knows about herself and her family. But is it even real?
