The new edition from the Author's Guild's backinprint.com program is an expanded edition, which contains six chapters that were cut from the original 1946 edition for length. The new edition has the original illustrations by Olive Bailey. It also has the original cover art.
In the middle of a deep forest is an enchanted valley and a castle where only shadows live, shadows of kings and queens who have waited for hundreds of years for the spell cast upon them to be broken. One day, a girl named Lucy follows a little dog through a tunnel into the valley and meets the mysterious red-haired Michael, who takes her into the shadow world to meet Prince Mika and his mortal wife Gloria, their children and their children’s children, and learn the magic that will lift the spell.
