This book definitely has to be rated as an entire experience. From the beginning we know there is going to be fighting and some inconsistencies in the story, which makes it hilarious to me. You can easily tell which characters each author prefers. Comments between the chapters explain where the author wants the book to go. Sometimes they ignored the advice and sometimes the advice was used dramatically. Like when I hit chapter 14, I had to set the book down I was laughing so hard. Lisa gets the last chapter and tells David "I have been doing this longer" which shows to be true as she wraps the story up beautifully. Still dying over the plane crash that took the entire book to figure out. And I also still need to google some of David's vocabulary words although Lisa claims even she gave up on looking some of the words up. "If spell check doesn't recognize the word don't use it!" A completely different reading experience that I recommend as long as you keep an open mind and do not necessarily only focus on the story.
