It’s hard to put into words the emotional roller coaster I went through listening to this book on audible. I thoroughly enjoyed the format of letter writing to tell the life story of Sybil. The stories of each family member and friends told in real time correspondents allows the reader/listener to feel a connection to the people in Sybil’s life. It’s both heartbreaking and heartwarming and keeps the reader/listener engaged and vested in each character’s life. I was so sad at the end but felt triumphant for Sybil. I highly recommend.
