But suddenly she gets the feeling that she her secret place may not be a secret after all. There is someone else who appears to not only know about the barn but also seems to visit there regularly. The thirteen-year-old girl and her twin brother, Johnny, set out to find who the intruder is. In doing so, Mary Beth and Johnny are faced with a dilemma - whether to obey their parents, or do what they feel is right even if it might make their parents unhappy or angry with them. And through all this, Mary Beth realizes that Johnny isn’t the insensitive brother who always plays pranks. There is also another side of him that is compassionate, caring and understanding – the side that she had known all her life and the side that she can trust.
It is a great read for a teenager. It describes in great detail the Amish way of simple living that doesn’t consist of things like electricity, a television or even a telephone– things that non-Amish people (or Yankees as the Amish call us) may consider necessities. The bond between the brother and sister that is re-created during the summer when they try to unfold the secret of the intruder in the barn is beautifully described.
