A Tale Dark and Grimm

In this book Hansel and Gretel travel together and find themselves in very bad situations as they run away from the kingdom of Grimm thinking that their mother and father cut their heads off on purpose. Later they figure out that their parents actually cut their heads off because they had a servant named faithful Johannes that was turned to stone and his spirit asked Hansel and Gretel's father to cut their heads off so faithful Johannes could come back to life. Hansel and Gretel return to their home and find out that there's a dragon attacking the kingdom and it's possessing one of the townspeople. They devise a plan to defend the kingdom and defeat the dragon so they can live in peace. THERE IS ONE MORE SUPRISE I WILL NOT TELL YOU ABOUT!!!!!! Mwahahahahaha! (P.S. THE KING IS THE DRAGON!!)
