I loved this book lol anyway the problem in the book was all the people/ characters in the book who were "evil" and how they solved it was trying to become it's friend or fighting and defeating it. The two main characters were Jesse and Leslie who were best friends. They both have big imaginations and decided to build a secret land together.
Many animals and people take up residence in places and structures vacated by others, illustrating a phenomenon that economists and sociologists call a "vacancy chain."
