I love this book. I've never read a book which is written by two people, because I was afraid that the point of view and the plot will be confusing but this one changed my mind. I love both John Green and David Levithan's writing style. However, I was a bit disappointed with the ending, but the book overall is a very enjoyable read, It made me laugh in almost every chapter.
One of the books I could hardly put down until I finished it.
