Poppy Malone, a girl 9 1/2 years old, sees goblins, but the rest of her family does not believe her. It is very stressing for Poppy, so she decides to prove it. She follows a goblin into a cave and there she finds a goblin village. She is so excited that by accident she gets captured. She is clever to set a trail to find her way out, but the goblins are clever enough to switch her trail so that she goes in a circle. When she finds out how the goblins find their way around, she gets an idea and finds her way out!
