Have you seen a child eat too much sweet and it's energy level go up, and then it starts jumping, running, bouncing? This book is kind of like that. I don't know any other way to describe it. :P It's only 4th book of the series. I have to read 11 more books which are already published and more books are on the way to publish (hopefully). It is in this condition now, I am just wondering what will happen as the series goes by! 
 P.S. No point in saving a start for later.
