Living with their mother, they are trying to learn how to blend in and act like humans and most importantly, not be discovered. It’s tricky trying to unravel how humans interact with each other and to decipher how they show their emotions in so many different ways.When another message arrives from their dad, Zane and Finola find themselves at a castle, something they have never seen before, and they get involved in a family treasure hunt around the castle and its grounds.
