The World of the Unknowns: The Discovery.
That shed-like building on the school grounds was not there yesterday. As the three children were about to enter, they have no idea that it serves as a portal into the World of the Unknowns. A place of amazing powers and dark secrets held by children. A place that could never exist anywhere on Earth, from which no one has ever returned. More
On the way to school Bradley, his twin sister Megan and their friend and neighbor John find a small shed-like building that was not there before. They don't know that it serves as an portal into another world, the World of the Unknowns. When the three get transported into this world, little by little they realize how much the World of the Unknowns offers: a lot of fun things to do and capabilities one has never heard about in the real world – flying, like a bird, without an aircraft, going through walls, transporting over long distances in no time… However, with those skills also come many unpleasant rules from the Unknowns, then the disastrous discovery that they can never return home. What choices will Bradley, Megan and John make? This is the first book in the series of the World of the Unknowns where it is introduced and we begin to enjoy the adventures undertaken by Bradley and Megan and their friends.
