A brilliant, deeply dedicated psychologist, Grace Blades has a gift for treating troubled souls and tormented psyches--perhaps because she bears her own invisible scars: Only five years old when she witnessed her parents' death in a bloody murder-suicide, Grace took refuge in her fierce intellect and found comfort in the loving couple who adopted her. But even as an adult with an accomplished professional life, Grace still has a dark, secret side. When her two worlds shockingly converge, Grace's harrowing past returns with a vengeance.
