I guess I always give 5 stars to memoirs. I am a memoir addict, but I also write the personal essay and some fiction and teach creative writing. Authenticity and voice are aspects of good memoir writing.
I do not belong to that group of people who think memoir is a solipsistic form. The Rules of Inheritance, Claire Bidwell Smith, is a worthy read. Everyone’s story is the same but different, as is loss and sadness. It is honest, poignant, poetic, and well crafted. She’s not a victim, but portrays true loss and then gradual emergence into finding her truer self. I recommend!
