Rating this book just 5 stars seems a bit unfair, makes me want to re-evaluate my whole rating system and the other books I've given 5 stars to. We need more stars for books like this one :)
Amazing story, very emotional read. After I reached 35% of the book, couldn't stop crying every 15 minutes. Reading the last 25% of the book, I cried all the way to the last chapter.
I don't know why I didn't read it sooner, I had been looking for a tearjerker like this one for a long time. The last book that made me this emotional was The Time Traveler's Wife in 2005.
