It's hard for two writers to come together on anything. I respect and admire authors who can work collaboratively on a novel, especially when they both have unique styles and voices. Loving both of the authors who worked on this novel, it should be no surprise that I loved this novel as well, although I thought the plot was a little meandering in places. 
 Great characters. Great development. And, like everything Green and Levithan have done before, it has the kind of quotes that slam you down to the floor and make you text all of your friends immediately because it was JUST SO TRUE. That's EXACTLY how things are.
