This is such a different book; the only things I can liken it to are The Beatles' songs or Monty Python. Ob-la-dee, Ob-la-da kept running through my head as I read this.
Wharton pushes the reader to think beyond the physical attributes of a book as the story follows the life of Nicholas Flood. The story oftentimes reads like a fable--fun and silly and full of unexpected turns of events. It has its share of tragedy and melancholy. For me, this book was about mortality, but I think a reader could interpret this story many ways.
This would be an excellent book for a discussion group.
