This stunning new coloring book by Johanna Basford takes readers on a inky quest through an enchanted forest to discover what lies in the castle at its heart. As well as drawings to complete, color, and embellish, there are hidden objects to be found along the way including wild flowers, animals, and birds, gems, lanterns, keys, and treasure chests. Beginning at the entrance to the forest, the journey progresses through woodland, rocky caves and tree-lined mazes, over streams and a waterfall, across the tree tops, to finally reach the castle.

Also hidden throughout the book are nine symbols. Readers must find all the symbols to unlock the castle door at the end of the quest and discover what lies within.
