(The only "spoilers" is part of a quote from the end of the book in the second paragraph.)
This book is so simple, yet very deep and beautiful. While it had a slow start and some plot points that seemed just a bit too convenient in the middle, everything else came together really nicely.
Simply put, this book is about the stories of five individuals that grew apart and came back together through their love of music and their band Ghost Tree. With a slight mystery throughout, everything wrapped up nicely and we see what can summarize the theme of the book: "a lesson in the only that that really mattered, forgiveness."
It's more of a 3.5 for me. I really enjoyed the book overall, but not enough for a solid 4 or to even round up. It's definitely an easy, entertaining read and I'm sure could be read much quicker. I thoroughly enjoyed it and love that the author is local to Pittsburgh and brought so many things to the book from different neighborhoods to Slippery Rock University.
