This was a great one to listen to on audio due to the anthology-like structure of the book. Every chapter highlights an anonymous Craigslist user who decided to share their life story with the author. The author also includes her own story and the impact these strangers have had on her life. I must warn you that many of these stories are tragic and do not have happy endings, however, I feel like many readers may find certain aspects of the various stories that resonate with them. Even if you can't relate to any of these specific stories, this book will definitely leave you with empathy for all the silent battles we as humans endure daily. My one major issue with this book was the amount of stories that involved infidelity.
