Initially this book was a little slow for me and I had to push myself to keep going until it got to the interesting part. After that I kept going because the inner dialogues are very entertaining and interesting to say the least.
I am not sure if I liked any of the female characters, even though their stories are interesting and somewhat interconnected. The bulk of the story is about what's in that letter and how it plays out with all these characters.
I did enjoy the complex relationships between some of the characters. Nothing is really what it seems nor is it as simple as we are often lead to believe in other books and Hollywood. Like Tess, Will and Felicity's close but complicated history and relationships.
The epilogue....of what could of been. I wasn't a fan, better to have left it off without knowing the optimistic futures the characters would have had, had the future happened differently.
