The Tree Seekers

Becky Harrington is having a bad day.
After discovering a map of their backyard in a mysterious magic book, Becky and her two younger brothers and twin sisters find themselves trapped in a strange land. But before they can go home, they must perform a confusing task: find a tree that doesn't look like a tree, and return it to a place they know nothing about!
After Becky becomes separated from her brothers and sisters, she encounters a group of wacky pigs who want her for their queen. And if that's not enough, money-hungry goblins, an egotistical fairy monster, a young man who shivers when it's not cold, and an assortment of animals and oddball characters wait to thwart the children's every move. Will they be able to overcome these obstacles and make it home safely?
