The second in a series of light fantasy chapter books set in Morgantown, a town on the border between the real world and the magical world, by the authors of the Publishers Weekly bestselling BAILEY SCHOOL KIDS—a series of 50 books with more than 30 million copies sold!

“I need your help, Natalie,” Mr. Leery said. “Yours and Penny’s and Luke’s.”

Natalie is surprised to learn from her neighbor, Mr. Leery, that her classmates Penny and Luke are apprentice Keyholders. A Keyholder’s job is to guard the border between the real world and the magical world. Natalie is even more surprised when she finds out that she could be a Keyholder too—if she forms a “link” with a rat named Buttercup.

Will Natalie choose to join the Keyholders? Can she, Penny, and Luke learn how to work together with their links and protect the border from the goblins sent by the evil Queen of the Boggarts?
