The three children have differing opinions about their mother. Lucia is sure that she is dead, while Max feels that she is missing and will one day reappear. Otto has nothing to say, or sign, about it. Perhaps he is keeping a secret! One of the three is the narrator, but we are not privy to who is telling their story. I was constantly making new guesses of my own as I read. I might know, but maybe not.
When their father goes on one of his many long trips, and their caregiver in London is not there when they get there, the children decide that adventure is the name of the game, and go off on their own. Castle Folly holds secrets and a grand dose of the adventure they (well, Lucia) have been seeking. While this part of the story holds excitement and trepidation, it also brings the siblings closer together. The bonds are tighter, the secret uncovered and readers have a memorable story full of great writing, compelling characters and a deep and lasting love.
I read this book because I had so enjoyed The Humming Room, and I am glad that I did.
