That's Edna's Gift by Susan Rudnick

Susan Rudnick has friends in Davis and is using her visit with them to also have a book signing at Avid Reader -- which is how Lois connected with her.  So Lois' first guest in this new "local author" series is actually from  New York!  

Susan is on a tour to promote her new memoir "Edna's Gift: How My Broken Sister Taught Me to Be Whole".  This book recounts not only many experiences of Susan and her younger sister Edna, but it also delves into the effect their relationship had on Susan all her like.  While never living a "normal" life, Edna lived a life full of joy and inspiration.  

"For over forty years Susan Rudnick, LCSW, has been listening to people tell their stories in her Manhattan practice of psychoanalysis and psychotherapy. In Edna’s Gift she tells hers. Susan, a Zen practitioner, has published haikus as well as articles about psychotherapy in professional journals. She and her husband live in Westchester NY, but often love to spend time at their cabin in the Catskills. Being a parent is her greatest joy." (from the bio on her website,  SusanRudnick.com )
