In her memoir, 'The Beauty in Breaking,' Dr. Michele Harper writes about treating gunshot wounds, getting punched in the face, and discovering evidence of child abuse. She's also drawn insight and courage from her patients as she's struggled to overcome pain and trauma in her own life — growing up with an abusive father, and coping with the breakup of her marriage. Book critic Maureen Corrigan reviews 'Mexican Gothic' by Silvia Moreno-Garcia.
