Avery's family has just moved to the Pacific Northwest countryside. She explores the forests outside her home and in the woods she stumbles into a magic fairy circle which shrinks her. A young fairy named Birch agrees to help her reverse the magic on the condition she helps with plant gathering duties for the imminent full moon festival. She must befriend Birch and find the fairy village quickly if she wants to return home before her parents discover she is missing.
