Beyond the Hidden Door

Septimus and Astrid are grounded for trying to sneak out to a party. When they have to clean a personal library as part of their punishment, they accidentally discover a hidden catch... which leads to a mysterious door, one that disappears once they step through it. And so begins their first adventure in an attempt to get back home. Along the way, they encounter bizarre people and animals, but what they fail to realize is that the world they entered is no ordinary world, and getting back is practically impossible.
