I saw this book in Anthropologie, so of course, I downloaded it in the store on my Kindle! This is a good girlie, BFF kind of book. P.S. is a series of short-stories/letters penned by various freelance authors to women who have been meaningful in their lives. The best friend role is a complicated one in that it bears many similarities to dating/long-term intimate relationships. Like with boyfriends or partners, BFF's can break up suddenly or over time. These unsent letters describe a gamut of circumstances, from goodbye letters to best friends who have died of cancer to angry, hateful letters to BFF's who have stabbed the writer in the back. I found it interesting to read each story as some were tearjerking, emotional sentiments and others were funny or bitter. This book is for any woman who knows the value of a best girlfriend, one with whom you can trust your deepest secrets, laugh over stupid inside jokes, cry about painful experiences, finish the other's sentences, and pick-up mid-sentence after answering a phone call, as if no time has passed.
