What I would give for either a longer book or a second book. I love having multiple main characters and different POV's, but when the book ends, it leaves me wanting more of each character.
Aside from that I have never read dialougue that was so playful. It made the book so much more entertaining. Plot was great and I can only imagine how much thinking and consideration went into the story line, the different characters, sequence of the chapters, etc. Great book.
