I think this got off to a bit of a shaky start, with generic and not-very-engaging characters and some rather pedestrian prose (I mean, I realize this book is meant for younger readers, but as this is John Green I had higher expectations). But at the turning point of the book it begins to examine some more interesting subject manager, and in doing so it makes the characters more interesting. By the end I found I really liked the book. I didn't enjoy it as much as Paper Towns, but I liked it well enough.
