This book lends itself to audio format, which makes the letter writing more interesting. I love the letter writing format but the main character’s flaws might have made the story a bit boring and Sybil too annoying. Sybil is cold and abrupt with most people. Thankfully, the plot contains a redemption arc as she was wearing thin on me for a while. Overall, the writing is good and the narration was very good, so I would recommend this audiobook.
