Enchanted Castle 

Three children and their governess discover magic and mayhem when they stumble upon an abandoned castle in this delightful children’s story. While on vacation in the English countryside, Kathleen, Jimmy, and Jerry—together with their permissive French governess—decide to go exploring. They find a tunnel that leads to an old castle and have fun pretending the place is enchanted. But after discovering a maze and magical ring, they learn how perilous magic can be! Originally published in 1907, The Enchanted Castle is a timeless tale of make-believe and magic from the beloved children’s author, E. Nesbit.
