It is a story about a twin boy and girl who go on many adventures with their dad. There is adventure of a different kind in an "all of a sudden" moment when reality changes to fantasy. A second "all of a sudden" moment occurs when they come back to reality. There is also a life lesson in each story. The Little Red Door is about an adventure in their new house as they explore. It is fun, exciting, and suspenseful. It also is a good segue to bedtime with message after the end that "all of a sudden, it's bedtime!"
