In this book Princess Bubblegum has to deal with a royal issue that happens once every ten years. We have the chance to get to know our princess doing what she does the best: use her algebraic brain and rule her kingdom wisely. We met some charismatic characters -other kingdom ruler's friends of PB- and enjoy an awesome Peppermint Butler who's constantly playing some kind of dark magic as usual. I loved every page of the book, the script and the art. Also, the end is perfect!
