When Virginia Nalle wishes for a kitten, she wakes up with a baby cougar in her bed. The corn on the Biscorner farm transforms into marshmallow plants overnight when their son wishes for an endless supply of marshmallows. And when a mysterious hot air balloon appears on the Bergers' porch, Mr. Berger almost dies on its maiden voyage. The wishes in Hope's End are going awry, and it might be all Kitsy and Teddy's fault.

Or is someone else wreaking havoc? When the High Wish Granter calls them back to Lunia, brother and sister must trek to the Dark Lands and find out.
