Johnny's treehouse

Johnny Finley is the youngest in the family–his sisters are 10 years old and don’t always play with him. One day, they move from the city to a big country house where there is plenty of room to play. When Johnny discovers an old broken treehouse, he immediately becomes determined to have it for himself. His 5th birthday is coming up, and he hopes his dad will get it ready for then. But will he have time?
