As always, I was pleased with John Green. I have been (for whatever reason) reading his books backwards in order of publication. If I had not known the order of publication it would still be clear in what order his books were written. Which, I except as his improvement in his writing. The words that come to mind for his books: Profound, humorous, and captivating.
I have heard more positive things about this book than I did about any of his others (aside from TFiOS of course), which is why I had "slightly high" expectations. For the most part I enjoyed the characters, and I enjoyed the scenes where both the idea and the mood of the scene spoke louder than the story, which by the way, was the part of his book I found weakest.
And so, I give this book 3.5 stars.
