I read this book because my friend talked about it and said it was good even though it was written in the form of letters, emails, IMs, phone messages, chat rooms, etc. I was intrigued. I really enjoyed Ahern's P.S. I Love You so I figured it was worth a try. I can tell you now that Ahern is not a one hit wonder. This woman knows how to write so you laugh, cry and wanted to strangle the characters. I would now say that I'm a fan and plan on reading more of her work. 
 I can't decide whether or not to keep this book. I mean I really loved it but I'm also torn because at the same time I hated it too. Not because it was bad but just mostly how the story went and all the imaginings I had in my mind were nothing like the story. Still I loved the story because it was a very realistic romance and all involved took into the account of people they could hurt. It wasn't about cheating or flinging off responsibility to be with someone regardless of children or spouses. My biggest issue is I literally cried when it ended. It was very emotional and beautiful all at once. 
 We do get to live with Rosie through the communications over her life and some of the best ones are when her father actually participates in the writing and her bouts of silly conversations with Alex. 
 Rosie is a very strong woman who ends up dealing with a lot in her life. Her life is no picnic and she does complain but she picks herself up and tries with the support of friends, family and that best friend in the U.S. Some of Rosie's best moments are when she has no choice but to believe in herself and do what she's dreamed of and when she and her daughter are having fun. 
 Alex is a great guy but we don't get to see much from his POV because this story is mostly about Rosie. The thing is you realize that Alex is the type of guy to drop everything for those he loves, which he does for Rosie more than once. 
 It is a beautiful friendship that you hope will be more but to know what happens you should really read the book because it is worth every word. While this story would be classified as a romance because of the feelings involved, I think it is a story about friendship and best friends.
